Publishing runtime screenshots for museum documentation

Character-style prompt reviewed 2026-07-26

The exact zmacs-character-style-prompt.png capture was reviewed for Inks, faces, and character styles in Symbolics Genera. Its purpose is scholarly and transformative: it makes the source-derived distinction between semantic styles and concrete fonts checkable against one live editor state. The display is predominantly functional—a blank editor surface, one researcher-written test line, a mode line, and a short generated prompt—and contains no source, manual or Help prose, extracted font sheet, artwork, or user data. One full client frame is used because the editor, prompt, mode line, and who-line relationship are the visible claim; no interaction sequence or gallery is published. The image cannot substitute for Genera, its licensed media, documentation, font assets, or editor functionality. All four section 107 factors therefore support this limited use. This conclusion does not approve the other raw captures from the session or decorative reuse.

Reimplementation-specification reuse reviewed 2026-07-19

The exact lisp-listener-multiple-values.png and dynamic-lisp-listener-multiple-values.png files were separately reassessed for the Lisp Listeners and editable input reimplementation specification. That page uses one frame from each system beside narrower analysis of the visible Listener regions, input cursor, value-line ordering, and release-specific window substrate. It adds no pixels, source, Help prose, or decorative use. The two frames are the minimum needed to make the cross-release visual contract checkable and do not substitute for either system. The capture-specific conclusions above therefore support this additional scholarly use. This paragraph approves no other screenshot for specification reuse.

Program-selection specification reuse reviewed 2026-07-19

The exact CADR and Genera system-menu.png files were separately reassessed for the program selection, activities, and window management reimplementation specification. That page uses one sparse frame from each system to compare the visible displayed menu state: placement, three-column organization, labels, current item box, and bottom pointer documentation. The Genera frame additionally establishes its title, border, and drop shadow; those features are not attributed to the CADR frame. The surrounding startup and Listener text is incidental context. The reuse adds no pixels, source, Help prose, or decorative use. The images do not establish the invocation gesture, target-window or registry identity, registry dynamism, selection/reuse/create order, callback order, destructive-operation results, or layout identity and persistence; those claims remain action-log-, source-, or runtime-trace-grounded. These two exact frames are the minimum reviewed images needed to make the release-specific visual contract checkable. This paragraph approves no other screenshot for specification reuse.

Interface style-guide reuse reviewed 2026-07-26

The exact CADR and Genera system-menu.png files and the exact Genera accepting-values-gc-options.png file were separately reassessed for the CADR and Genera interface style guide. The guide uses the two System Menu frames for direct cross-system criticism of visible typography, popup density, columns, current-item outlines, frame/status relationships, and the release-specific absence or presence of a hard lower-right shadow. It uses the Accepting Values frame to make the source-grounded Genera form language—textual grouping, indentation, inline alternatives, face changes, printed actions, and stable pointer documentation—visually checkable. The current GC values are explicitly excluded from the claim.

No new pixels, crop, interaction sequence, source, Help prose, manual text, artwork, or extracted font asset is added. These three sparse functional frames are the minimum needed for the article's comparison; the surrounding Listener and startup text is incidental context. The images cannot substitute for the systems, font packages, documentation, or operational UI. Their use is analytical and instructional rather than decorative: the guide expressly forbids treating them as templates, wallpapers, or a general gallery. The capture-specific conclusions above therefore support this additional scholarly use. This paragraph approves no other screenshot or reuse.

D03 Screen Editor and Frame-Up specification reuse reviewed 2026-07-19

The exact CADR screen-editor-menu.png, Genera screen-editor-menu.png, and Genera frame-up-split-layout.png files were separately reassessed for the Screen Editor and Frame-Up layout design reimplementation specification. That page uses the two menu frames only to constrain the visible release-specific operation inventories, ordering, label/styling, current item, short pointer documentation, and surrounding-screen relationship. It uses the Frame-Up frame only to constrain the researcher-created two-display-pane model, pane labels, horizontal divider, short typed command transcript, and title/display/interactor/menu regions.

The reuse adds no pixels, source listing, extracted Help, or decorative gallery use. The images do not establish input dispatch, raw button precedence, object identity, snapshot freshness, geometry algorithms, mutation, Undo, cleanup, presentation-menu contents, generated forms, Preview, or source-to-world/build identity; those claims remain source-, action-log-, trace-, or explicit-oracle-grounded. These three exact frames are the minimum reviewed images needed to make the D03 cross-release visual contract checkable. This paragraph approves no other screenshot for specification reuse.

D04 Emergency Break specification and Genera capture reviewed 2026-07-19

The exact Genera emergency-break-arithmetic-evaluation.png file was reviewed for the first time, and the already-published CADR emergency-break-cold-load-evaluation.png file was separately reassessed for the Emergency Break and degraded interaction paths reimplementation specification. The following four-factor conclusion is specific to those exact files on that D04 page.

1. Purpose and character. The D04 specification uses one observed recovery frame from each runtime-observed system profile to criticize and explain how interaction changes when the ordinary window substrate is unavailable. The Genera frame verifies the separate cold-load client, Emergency Break and breakpoint identity, cold-stream Break evaluation protocol, and researcher-entered arithmetic result. The CADR frame verifies the materially different primitive overlay and saved-listener relationship, including the documented runtime limitation on Resume delivery. This nonprofit historical and compatibility-analysis purpose is evidentiary, not decorative or a substitute user interface. This factor strongly favors the two reviewed uses.
2. Nature of the displayed work. The Genera image is a sparse functional console: a short recovery heading, package and breakpoint status, one short operational instruction, the project-entered (+ 40 2) probe, 42, a prompt, and otherwise blank space. It contains no artwork, source, font sheet, Help page, manual prose, user data, or third-party media. The CADR image likewise documents primitive recovery text and the same synthetic probe over the functional saved screen. This factor favors the reviewed uses, while recognizing that particular screen expression may still be copyrighted.
3. Amount and substantiality. D04 uses one still for each of its C303 and G85 runtime-observed profiles; no C46 runtime image is claimed. The complete 1024-by-768 Genera cold-load client is retained because its independent-client boundary, position of the small text region, and overwhelming blank area are part of the visual contract; nearly all pixels are empty and cropping to the text would erase that evidence. The one existing CADR frame is needed to show the contrasting overlay relationship. Neither image is part of a sequence or gallery, and the pair is a minute portion of two large interactive systems. This factor favors the reviewed uses.
4. Effect on the market. Neither still can execute a break loop, provide the licensed world or public load band, reproduce source or documentation, expose a command corpus, or replace any software or screenshot-licensing product. Their value comes from the surrounding provenance, source comparison, and conformance analysis. This factor strongly favors the reviewed uses.

On balance, the Genera image may be published and both exact images may be embedded in D04 under this case-specific fair-use rationale. The approval adds no pixels or licensed payloads, extends no repository license to either screen, and does not approve either file as a generic illustration, any additional screenshot, richer debugger or Help screens, or reuse outside the analyzed purpose.

D05 editor-family specification reuse reviewed 2026-07-19

The exact CADR zmacs-lisp-buffer.png, zwei-help-menu.png, zmacs-text-mode.png, and zmacs-lisp-mode.png files and the exact Genera zmacs-editor-menu.png, zmacs-help-dispatcher.png, and zmacs-two-window-layout.png files were separately reassessed for the EINE, ZWEI, and Zmacs editor-family reimplementation specification.

The D05 page uses the four public-system observations to constrain initial editor geometry, the staged Help state, and a mode transition. It uses the three Genera observations to constrain the editor menu, Help state, and two-pane relationship. The images sit beside source-grounded criticism and conformance requirements; none is a decorative illustration or operating substitute. The Help frames contain only the one functional dispatcher state needed to identify the multistage interface, not a navigable Help corpus.

Seven complete frames are proportionate because each supplies a distinct visual state across two release profiles; D05 publishes no full or step-by-step interaction sequence, EINE facsimile, source listing, font sheet, manual page, or additional Genera output. The frames cannot provide the editors, public band, licensed world, source, Help database, keymap or presentation registry. Their market value derives from the museum's provenance and analysis. On balance, the existing capture-specific conclusions support these exact scholarly reuses.

The images establish only the visible anchors named on D05. They do not establish source-to-band/world identity, hidden table or translator ownership, command effects, complete Help prose, timing, undo, file mutation, exact fonts, or pixel identity. This review approves no other D05 screenshot or generic reuse and extends no project license to the screen displays.

D06 Edit Buffers captures reviewed 2026-07-19

The exact CADR edit-buffers.png and Genera zmacs-edit-buffers-marked-delete.png files were reviewed for the directory, difference, and buffer editors reimplementation specification. This conclusion is limited to those two files on that scholarly page and the closely linked factual dossier.

1. Purpose and character. D06 uses one runtime observation from each selected runnable profile to criticize and explain a material implementation change: System 303 exposes four independent action columns, while Genera exposes one per-row action character. The images make that release-specific visual contract independently checkable beside source, manual, and conformance analysis. They are not decorative application portraits or operating substitutes. This factor strongly favors the reviewed use.
2. Nature of the displayed work. Both captures are sparse, predominantly functional editor states: a heading, synthetic or default buffer names, status columns, a cursor, scrollbar, mode line, and otherwise blank space. They contain no source listing, artwork, user file, configured site data, third-party media, font sheet, or Help/manual prose. This factor favors the reviewed use while recognizing possible copyright in particular screen expression.
3. Amount and substantiality. One complete client frame per runtime profile is needed to preserve the relationship among heading, row model, action columns, mode line, and surrounding blank editor geometry. D06 does not publish the CADR Help screen, Dired login prompts, later mark/defect sequence, the Genera unmarked baseline, or the post-alias diagnostic frame. Two stills are a minute portion of the interactive systems and are not a navigable sequence. This factor favors the reviewed use.
4. Effect on the market. The two stills cannot execute Edit Buffers, perform a buffer action, supply the public load band or licensed world, expose the binding tables, reproduce documentation, or substitute for any software or licensed publication. Their value comes from the museum's provenance and comparison. This factor strongly favors the reviewed use.

On balance, the two exact images may be published for this D06 evidentiary use. The review does not approve the local CADR Help or U-defect captures, any Genera List Buffers image as a substitute for Edit Buffers, a Dired login prompt as a directory-listing illustration, destructive action execution, bulk reuse, or a project license in either screen display. Pixels establish only the visible states; input dispatch and the Genera d transition additionally rely on the recorded action log, while the older CADR session remains explicitly intermediate evidence.

D07 Help and Document Examiner captures reviewed 2026-07-19

The exact CADR zwei-help-menu.png and Genera zmacs-help-dispatcher.png and document-examiner-initial.png files were separately reviewed for the Help, self-documentation, and Document Examiner reimplementation specification. This conclusion is limited to those three files on that scholarly specification and the Help, self-documentation, and Document Examiner evidence dossier.

1. Purpose and character. D07 uses the two dispatcher images to compare the short, staged, release-specific editor Help surfaces with the source-defined effective trees, and the DEX image to make the Standard layout contract independently checkable. Each sits beside criticism of behavior manuals omit, provenance, nonclaims, and conformance tests. They are evidence, not decoration, advertising, operating substitutes, or a screenshot gallery. This factor strongly favors the reviewed use.
2. Nature of the displayed work. The frames are functional interface states: short dispatcher prompts, researcher-created or default editor content, sparse panes, candidates, labels, and menu items. They contain no source listing, artwork, third-party media, user data, font sheet, substantial Help/manual prose, or displayed Sage document body. This factor favors the reviewed use while recognizing possible copyright in screen expression and the licensed nature of the Genera runtime.
3. Amount and substantiality. One dispatcher frame per runnable profile is the minimum that preserves each complete staged choice surface; one Standard DEX frame is the minimum that preserves pane and menu relationships. The page does not publish a full interaction sequence, System/Terminal Help table, pop-up Help frame, Small DEX, computed DEX Help, search results, rich documentation, tutorial, source, or extracted payload. Three stills are a minute portion of two large interactive systems. This factor favors the reviewed use.
4. Effect on the market. The stills cannot execute a command, provide the CADR band or licensed Genera world, reproduce a manual or Sage corpus, expose complete bindings, substitute for software access, or replace a screenshot-licensing product. Their value arises from the museum's source/runtime comparison, provenance, and reconstruction tests. This factor strongly favors the reviewed use.

On balance, these three exact images may be published for this D07 evidentiary use. The review does not approve physical F12 as a Symbolics-keyboard fact, hidden option behavior, command effects, boxed DEX menu cells, the 950-pixel threshold, Small DEX, the pop-up Help frame, optional commands, richer documentation screens, the local System Help capture, bulk/generic reuse, or a project license in any screen display. The public CADR and licensed Genera artifact boundaries remain separate.

D08 ZMail and mail-composition captures reviewed 2026-07-19

The exact Genera zmail-reader-empty.png and zmacs-text-mail-template.png files were separately reviewed for the ZMail and mail composition reimplementation specification. This conclusion is limited to those two files on that exact scholarly page.

1. Purpose and character. D08 uses the empty reader to make the selected Genera 8.5 Zmail layout and menu contract checkable, and the blank Text Mail template to distinguish the separate Zmacs composition target from that reader. The images sit beside source/runtime comparison, implementation criticism, explicit nonclaims, and conformance tests. They are evidentiary research uses, not decoration, advertising, an operating interface, or a mail-content gallery. This factor strongly favors the reviewed use.
2. Nature of the displayed work. Both captures are sparse, predominantly functional interface states: empty panes, short labels and operational hints, a blank To/Subject form, a body separator, and a mode line. They display no mail message, recipient, source listing, artwork, third-party media, user data, font sheet, or substantial Help/manual prose. This factor favors the reviewed use while recognizing possible copyright in the particular screen expression and the proprietary nature of the Genera runtime.
3. Amount and substantiality. One complete 1200-by-900 state per target is the minimum that preserves the reader's pane/menu relationship and the distinct composition template and mode identity. D08 publishes no login, error, Help, mail-content, service-configuration, send, save, or transport-result sequence. The residual Zmail/dither region beside the Text Mail template is incidental and is not used to claim complete frame geometry. Two stills are a minute portion of the interactive system and are not a navigable substitute. This factor favors the reviewed use.
4. Effect on the market. The stills cannot read or send mail, execute commands, supply the licensed world or source, reproduce the Help or manual corpus, expose complete bindings, configure a site, or replace any software or screenshot- licensing product. Their value comes from the museum's provenance, comparison, and reconstruction tests. This factor strongly favors the reviewed use.

On balance, these two exact images may be published on the D08 specification for the uses above. Pixels establish only the named visible relationships; entry, Control-X M dispatch, internal ownership, state transitions, failure order, and transport behavior rely on the recorded action log and source evidence or remain named runtime oracles. This paragraph approves no other D08 screenshot, message content, richer Help or error screen, interaction sequence, generic reuse, or project license in either screen display, and it does not merge the licensed Genera evidence boundary with public CADR or LM-3 materials.

D09 Converse and Notifications captures reviewed 2026-07-19

The exact Genera converse-empty.png and notifications-synthetic-record.png files were separately reviewed for the Converse, direct messages, and Notifications reimplementation specification and its substantive historical evidence dossier, Converse, direct messages, and notifications on CADR and Genera. This conclusion is limited to those two files on those two exact scholarly pages.

1. Purpose and character. The two D09 pages use the untouched Converse frame to make the selected Genera 8.5 editor entry state and structural layout checkable, and the Notifications frame to distinguish the separate retained-history viewer after a controlled TV:NOTIFY call. The images sit beside source/runtime comparison, implementation criticism, exact input and state contracts, nonclaims, and conformance tests. They are evidentiary research uses, not decoration, advertising, an operating chat interface, or a message gallery. This factor strongly favors the reviewed uses.
2. Nature of the displayed work. Both captures are sparse and predominantly functional. The first contains a blank To: template, structural separator, scrollbar, cursor, and short mode-line directions. The second contains a title, two-item functional menu, scrollbar, and one timestamped record whose substantive text was written by this museum. Neither shows a real address or conversation, source listing, artwork, third-party media, private data, font sheet, or substantial Help/manual prose. This factor favors the reviewed use while recognizing possible copyright in the particular screen expression and the proprietary nature of the Genera runtime.
3. Amount and substantiality. One complete 1200-by-900 state per visible D09 application is the minimum that preserves the relationship among the panes, structural marks, menu, scrollbar, mode line, and surrounding blank space. D09 publishes no login, Help, real message, reply, delivery, failure, notification pop-up, network, or interaction sequence. Two stills are a minute portion of the interactive system and are not a navigable substitute. This factor favors the reviewed use.
4. Effect on the market. The stills cannot send or receive a message, provide the licensed world or source, reproduce the Help or manual corpus, expose the binding tables or protocol, configure a peer, or replace any software or screenshot-licensing product. Their value comes from the museum's provenance, comparison, and reconstruction tests. This factor strongly favors the reviewed use.

On balance, these two exact images may be published on the D09 specification and historical dossier for the uses above. Pixels establish only the named visible relationships and the presence of the researcher-authored record; selection, command dispatch, retention, delivery order, hidden object identity, polling, networking, and source-to-world identity rely on the recorded action log and source evidence or remain named runtime oracles. This paragraph approves no real message content, substantial Help, error or pop-up screen, additional interaction state, generic reuse, or project license in either screen display, and it does not merge the licensed Genera evidence boundary with public CADR or LM-3 materials.

D10 network-terminal captures reviewed 2026-07-19

The exact CADR supdup-disconnected.png and telnet-disconnected.png files and Genera terminal-disconnected.png file were separately reviewed for the network terminal applications reimplementation specification and the substantive historical dossier SUPDUP, Telnet, and the Genera Terminal program. The Genera image was also reviewed for its same limited evidentiary use in the normative System 452.1 Terminal companion. This conclusion is limited to those exact image-and-page combinations and to the caveated claims stated there.

1. Purpose and character. D10 uses the two CADR images to show the distinct source-injected Supdup and static Telnet shell labels and their shared TV full-screen relationship while criticizing the mismatch among maintained source, compiled band, and obsolete System-key documentation. It uses the Genera image to establish the live/manual prompt discrepancy, initial label, scrollbar and chrome. The stills sit beside release profiles, source/runtime criticism, complete input and protocol contracts, failure semantics, nonclaims and conformance tests. They are evidentiary research uses, not decoration, advertising, a remote-login service or a terminal gallery. This factor strongly favors the reviewed uses.
2. Nature of the displayed work. All three frames are sparse and predominantly functional. The CADR images show blank white terminal surfaces, two short labels, the generic who-line, and a visible text cursor in the Telnet shell only. The Genera image adds one short functional host prompt, a scrollbar and label. None shows Help/manual prose, source, a peer transcript, credentials, artwork, third-party media, private data, a font sheet or a successful connection. This factor favors the reviewed use while recognizing possible copyright in the particular screen expression and the proprietary nature of the Genera runtime.
3. Amount and substantiality. One complete frame for each distinct shell is the minimum that preserves each terminal surface, bottom label and who-line, the Telnet shell's visible text cursor, and the Genera scrollbar/prompt relationships. D10 publishes no login exchange, Help, options panel, negotiation, remote output, error sequence, file transfer or interaction gallery. Three inert stills are a minute portion of the systems and cannot reproduce their interactive behavior. This factor favors the reviewed use.
4. Effect on the market. The stills cannot open a connection, emulate a terminal, provide the source/load band/VLOD/manual, reveal the binding or protocol tables, or replace any software or screenshot-licensing product. Their value comes from the museum's provenance, comparison and reconstruction analysis. This factor strongly favors publication.

On balance, these exact three images may be published on the D10 specification and historical dossier for the uses above, and the exact Genera image may additionally be published on the named normative Genera companion for the same bounded use. The CADR images establish only explicitly source-injected/static shell appearance; they do not establish clean application loading, process startup, a host prompt, connection or source-to-band identity. The Genera image establishes only the initial disconnected visible state. This review approves no Help or options screen, connected peer content, error/debugger capture, future interaction sequence, generic reuse, or project license in the displayed material. MIT, LM-3, Symbolics and their contributors/rightsholders are identified for historical attribution only; no affiliation or endorsement is implied.

1. Purpose and character

The museum uses each selected image to establish what a preserved system actually displayed after a recorded interaction. The nearby prose explains the behavior, the capture identifies the release-bounded observation, and the image lets a reader verify details that source or manuals alone do not prove. The reviewed publication is a free museum knowledge-base use: scholarly and evidentiary rather than advertising, decoration, or a substitute user interface.

This factor strongly favors the reviewed uses. In Sony Computer Entertainment America v. Bleem, 214 F.3d 1022, the Ninth Circuit vacated a preliminary injunction against actual videogame screenshots used in commercial comparative advertising. Accurate captures were needed to communicate what the software displayed, even in a less favorable commercial setting. The Copyright Office provides a concise case summary.

The conclusion remains use-specific. In Andy Warhol Foundation v. Goldsmith, the Supreme Court emphasized the purpose of the particular challenged use, not new meaning in the abstract. That is why this policy requires a screenshot to sit beside analysis of the exact historical or behavioral claim it supports.

2. Nature of the displayed work

A software screen can contain copyrightable text or artwork. It can also be dominated by functional layout, methods of operation, short labels, status fields, and researcher-entered text. Section 102(b) does not extend copyright protection to a procedure, process, system, or method of operation, although a particular expressive depiction can still be protected.

The Copyright Office's Compendium, section 721.10, recognizes potentially copyrightable screen text, artwork, and photographs but also says registration should be refused where a screen-display claim rests only on layout or format, blank forms, de minimis menus, or purely functional elements. The reviewed application screens are primarily functional and factual. The ZWEI Help dispatcher contains more authored prose, so this factor is less favorable for that image, but the narrow analytical purpose remains strong.

3. Amount and substantiality

Most images reproduce one complete visible state because editor geometry, mode lines, mouse documentation, menu placement, or surrounding context are part of their evidence. Cropping those elements would impair those claims. The two Hardcopy images make the opposite capture-specific judgment: only the complete form is probative, so the unrelated underlying Listener and exploratory Debugger were removed. The selected stills are nevertheless a minute part of large interactive systems, and the site does not publish a navigable sequence or comprehensive screen catalog.

This factor favors the reviewed set. Sony v. Bleem treated a handful of full software screenshots as an insignificant portion of the interactive works. The Second Circuit likewise found fair use when complete copyrighted posters and tickets were reproduced at an appropriate scale as historical artifacts in an explanatory history in Bill Graham Archives v. Dorling Kindersley, 448 F.3d 605.

4. Effect on the potential market

These stills cannot operate CADR or Genera and cannot replace a world image, source tree, manual, font, help corpus, or other licensed product. Their value comes from the museum's provenance and analysis. Publishing this small set does not supply a substitute screenshot library or a substitute for licensing the systems themselves.

This factor strongly favors publication. The conclusion does not depend on copyright abandonment or on Symbolics material being public domain. The repository continues to treat Genera as proprietary and keeps the world, source, extracted payloads, and raw sessions local.

Runtime teaching animations

A guided-tour animation receives the same image- and use-specific review as a still, plus review of the sequence itself. It must be either a continuous recording or ordered action-boundary frames from one coherent harness interaction. Alternating unrelated before and after stills is not a demonstration and must not be published as one. A staged clip must not imply real-time timing or pointer motion that its frames do not retain.

Preserve the source pixels and canvas; do not fractionally rescale bitmap fonts or patterns. Record the session, actions, source-frame or raw-video identity, assembly tool, frame timing, loop behavior, animation digest, and exact instructional claim. An animation remains disallowed when it becomes a bulk gallery, reproduces substantial Help or manual text, or functions as a decorative reel.
