This policy covers copyright and licensing for the content hosted on RetroTechCollection: text, images, diagrams, schematics, software listings and other media.
This policy covers copyright and licensing on RetroTechCollection: the text contributors write, the photographs and drawings they make, and material by other people that is uploaded or quoted here, such as manuals, schematics and photographs.


== Purpose ==
== Your own work ==
The policy is meant to make sure that material on RetroTechCollection respects the rights of its creators, does not infringe copyright, and states clearly the licence under which it is made available.
Text you write on the wiki, and photographs, drawings and diagrams you make yourself, are released under the licences set out in section 4.1 of the [[RetroTechCollection:Terms of Use|Terms of Use]]: the Creative Commons Attribution-ShareAlike 4.0 International licence (CC BY-SA 4.0) and the GNU Free Documentation License (GFDL) 1.3 or later. Anyone may reuse it on those terms.


== 1. Scope ==
When you upload your own photograph or drawing, say on the file page that it is your own work and give the licence.
This policy applies to all content contributed by users or imported from external sources, including:
* photographs of hardware, screenshots, scans and diagrams
* excerpts from technical manuals, service guides and datasheets
* software listings, ROM code snippets and BASIC programs
* logos, trademarks and branding


== 2. Public domain and free licences ==
== Material by other people ==
=== 2.1 Public domain ===
Copyrighted material may be used and uploaded on RetroTechCollection, including complete service manuals, schematics, datasheets, photographs and excerpts, as long as it is cited. Citing it means stating:
Material in the public domain may be reproduced freely. It includes:
* the source: where the copy came from, such as a URL and the date it was retrieved, a publication, or who scanned or photographed it
* works whose copyright has expired (typically 70 years after the author's death, but this varies by jurisdiction)
* the author or publisher
* US Government works not subject to copyright
* the copyright holder, or "copyright holder unknown" where it cannot be established
* works explicitly dedicated to the public domain, for example under CC0


When using public domain content, state:
Give these on the file page of every upload, and in the article wherever the material is used, as a reference. See [[RetroTechCollection:Citing sources]].
<pre>
 
''This image/manual/page is in the public domain.''
Material by other people stays under its owner's copyright. It is not covered by the licences for contributors' own work, and RetroTechCollection claims no rights in it.
Source: [URL or reference]
</pre>


=== 2.2 Free and open licences ===
Public domain and freely licensed material (Creative Commons, GFDL, MIT, BSD and similar) is cited in the same way, and its file page gives the licence. Follow the licence's own attribution terms.
Content under a compatible free licence may be used, provided the attribution and licence terms are honoured. Accepted licences are:
* Creative Commons Attribution (CC BY)
* Creative Commons Attribution-ShareAlike (CC BY-SA)
* GNU Free Documentation License (GFDL)
* MIT, BSD or similarly permissive text licences


Include a clear licence statement on the page or file description:
=== File pages ===
Every file page says what the file is, where it came from, who made it, and its licence or copyright holder:
<pre>
<pre>
Licensed under [https://creativecommons.org/licenses/by-sa/4.0/ CC BY-SA 4.0].
== Summary ==
Source: [URL or reference]
Apple Computer, Macintosh Plus Service Source, 1995 edition.
</pre>
 
== Source ==
Scanned by the uploader from a printed copy.


== 3. Fair use and non-free content ==
== Author ==
RetroTechCollection discourages non-free content unless it is strictly necessary. It is permitted only if:
Apple Computer, Inc.
# no free alternative exists;
# the use is minimal and illustrative, for example one diagram from a manual;
# the use adds significant new context or commentary (it is transformative); and
# you provide a description of the work, the purpose of the use (for example critical analysis or documentation), the amount used (for example one figure), and a justification of fair use under US law or the local equivalent.


Use the {{tl|Non-free}} template on pages containing fair-use content:
== Licence ==
<pre>
Copyright Apple Computer, Inc.
{{Non-free
| source = ''Commodore SX-64 Service Manual'', 1984, electroluminescent display schematic
| rationale = Illustrates the EL backlight circuit; no free equivalent available.
| resolution = 600×400px
}}
</pre>
</pre>
The template also accepts <code>author</code>, <code>permission</code> and <code>license</code>.


== 4. Uploading and attribution ==
For your own photograph:
=== 4.1 Local vs. Commons ===
* Upload locally when fair use or non-free restrictions apply. The file stays on RetroTechCollection's servers.
* Upload to Wikimedia Commons for public domain or freely licensed content. This is preferred, because it makes the file easier to find and reuse. Files on Commons can be used on this wiki directly by name.
 
=== 4.2 Required information ===
When uploading any media, include:
* the title and a description of the work
* the author or creator
* the source URL or publication reference (manual name, date, page)
* the licensing information (public domain, CC BY-SA, or a fair use rationale)
 
Example file description:

== 5. Text content and excerpts ==
[[Help:Uploading service manuals]] covers the page each hosted manual also gets.
Text on RetroTechCollection should be:
* original writing, or paraphrased summaries of sources
* limited quotations (no more than 10% of freely available text) with clear blockquote markup and attribution


For longer technical excerpts, such as code listings and register tables, prefer linking to an external public domain or freely licensed PDF, or host it on Commons under an appropriate licence.
=== Quoting text ===
Article text is normally written in your own words. When you copy text from a source, such as a procedure or a table from a manual, mark it as a quotation or say that it is reproduced from the source, and cite it.


== 6. Trademarks and logos ==
=== Diagrams you redraw or annotate ===
Registered trademarks (for example "Commodore", "Atari" and "Sega") remain the property of their owners. Permitted uses are:
Credit the original (source, author or publisher, copyright holder) and say which parts are your additions.
* identifying the subject of the page (nominative fair use)
* low-resolution logos for identification in infoboxes or galleries


Always include:
=== Trademarks and logos ===
<pre>
Trademarks such as "Commodore", "Atari" and "Sega" belong to their owners. Use them to identify the subject of a page. Logos may be used to identify a manufacturer or product in infoboxes and on category pages, cited like any other image.
''"XYZ" is a registered trademark of XYZ Corporation. Used here under nominative fair use for identification purposes only.''
 
</pre>
=== Wikimedia Commons ===
Files on Wikimedia Commons can be used on this wiki directly by name, without uploading them again. Commons accepts only freely licensed files, so upload copyrighted manuals and photographs here instead.


== 7. Derivative works ==
=== Software ===
When creating diagrams, schematics or annotated images, either base your work on public domain or freely licensed originals, or substantially transform the copyrighted material (for example by redrawing, colouring or annotating it). Credit the original source and make clear which parts are your additions.
The upload form accepts documents, images, audio and video. It does not accept ROM images, disk images or program files.


== 8. Takedown and enforcement ==
== Removal requests ==
If you believe content on RetroTechCollection infringes copyright:
If you hold the copyright in material on RetroTechCollection and want it removed, or its credit corrected:
# Open a ticket on the [https://forum.retrotechcollection.com/tickets/ RTC Forum] or email [mailto:[email protected] dmca@retrotechcollection.com], giving:

This policy covers copyright and licensing on RetroTechCollection: the text contributors write, the photographs and drawings they make, and material by other people that is uploaded or quoted here, such as manuals, schematics and photographs.

Your own work

[edit source]

Text you write on the wiki, and photographs, drawings and diagrams you make yourself, are released under the licences set out in section 4.1 of the Terms of Use: the Creative Commons Attribution-ShareAlike 4.0 International licence (CC BY-SA 4.0) and the GNU Free Documentation License (GFDL) 1.3 or later. Anyone may reuse it on those terms.

When you upload your own photograph or drawing, say on the file page that it is your own work and give the licence.

Material by other people

[edit source]

Copyrighted material may be used and uploaded on RetroTechCollection, including complete service manuals, schematics, datasheets, photographs and excerpts, as long as it is cited. Citing it means stating:

  • the source: where the copy came from, such as a URL and the date it was retrieved, a publication, or who scanned or photographed it
  • the author or publisher
  • the copyright holder, or "copyright holder unknown" where it cannot be established

Give these on the file page of every upload, and in the article wherever the material is used, as a reference. See RetroTechCollection:Citing sources.

Material by other people stays under its owner's copyright. It is not covered by the licences for contributors' own work, and RetroTechCollection claims no rights in it.

Public domain and freely licensed material (Creative Commons, GFDL, MIT, BSD and similar) is cited in the same way, and its file page gives the licence. Follow the licence's own attribution terms.

File pages

[edit source]

Every file page says what the file is, where it came from, who made it, and its licence or copyright holder:

== Summary ==
Apple Computer, Macintosh Plus Service Source, 1995 edition.

== Source ==
Scanned by the uploader from a printed copy.

== Author ==
Apple Computer, Inc.

== Licence ==
Copyright Apple Computer, Inc.

For your own photograph:

== Summary ==
Commodore 64C motherboard (ASSY 250469).

== Source ==
Own photograph, May 2025.

== Author ==
[[User:YourUsername]]

== Licence ==
[https://creativecommons.org/licenses/by-sa/4.0/ CC BY-SA 4.0]

Help:Uploading service manuals covers the page each hosted manual also gets.

Quoting text

[edit source]

Article text is normally written in your own words. When you copy text from a source, such as a procedure or a table from a manual, mark it as a quotation or say that it is reproduced from the source, and cite it.

Diagrams you redraw or annotate

[edit source]

Credit the original (source, author or publisher, copyright holder) and say which parts are your additions.

Trademarks and logos

[edit source]

Trademarks such as "Commodore", "Atari" and "Sega" belong to their owners. Use them to identify the subject of a page. Logos may be used to identify a manufacturer or product in infoboxes and on category pages, cited like any other image.

Wikimedia Commons

[edit source]

Files on Wikimedia Commons can be used on this wiki directly by name, without uploading them again. Commons accepts only freely licensed files, so upload copyrighted manuals and photographs here instead.

Software

[edit source]

The upload form accepts documents, images, audio and video. It does not accept ROM images, disk images or program files.

Removal requests

[edit source]

If you hold the copyright in material on RetroTechCollection and want it removed, or its credit corrected:

  1. Email [email protected] or open a ticket on the RTC Forum.
  2. Give the page or file name, identify the work and your right in it, and give your contact details.

The material will be removed, or the credit corrected if that is what you ask for. RetroTechCollection:Copyright violations gives the full procedure and timings.
