Software is more than source code. A project also includes release notes, installation instructions, API references, issue discussions, diagrams, build requirements and the knowledge that connects them. When a developer website disappears, the repository may survive while the information needed to understand or use it becomes scattered across old links and archived pages.
TwoSquares helps organisations and software communities recover and republish historical technical documentation. This work is suitable for older open-source projects, unsupported software products, discontinued services and technical websites with valuable archives. We focus on provenance, usable navigation, search continuity and appropriate rights, not on pretending a discontinued product is actively maintained.
The problem with vanishing project websites
A user searching for a function in a specific library release may find a reference to an old Doxygen page. A support article may link to a source archive that is no longer hosted. A system integrator may need documentation for a product still deployed in production, despite its original publisher having closed.
Publishing a glossy new homepage does not answer those questions. Historical materials must be connected to the correct version, project and source. A release from 2010 is not interchangeable with modern code; a newly written overview is not the same as the original API manual.
What our technical preservation work can include
Project and URL archaeology
We identify old domains, subdomains, URL patterns, project versions and externally cited technical references. Link data, source repositories and web archives can help reveal material absent from a surviving sitemap.
Source and documentation recovery
We investigate available repositories, release packages, archived documentation, file exports and surviving copies from publishers or maintainers. Every recovered item should have recorded provenance. We do not infer a file's contents or authenticity from its filename alone.
Documentation reconstruction
Where original materials are recoverable and their licences allow use, we can build readable indexes, restore navigation and identify relevant versions. If a page needs to be rewritten, new editorial guidance should be labelled as such and kept separate from the original manual.
Stable reference pages
A missing download cannot always be replaced, but a precise source record can still help. It should explain the project's identity, intended version, where authorised copies might be found and what remains unverified. This is preferable to redirecting a specific technical citation to an unrelated sales or services page.
Technical SEO and search continuity
We can map historically important URLs, audit internal links, plan direct redirects for genuine equivalent resources and maintain XML sitemaps for accessible documentation. See website migration and SEO recovery.
Preservation handover
Deliverables can include a file manifest, source register, link map, captured copies where lawful, an explanation of missing resources and guidance on ongoing maintenance. The aim is to reduce dependence on a single developer or hosting account.
A relevant independent project: GNU Telephony
The former GNU Telephony website illustrates the challenge of preserving older open-source documentation. Official GNU pages continue to explain the GnuComm ecosystem, while historic site references may lead to older wiki pages, release files and technical manuals. Our independent GNU Telephony project record documents the approach and known sources without claiming official maintainer status or a complete recovery.
Related research in our digital preservation hub covers file integrity, metadata, tool selection and the importance of respecting original publication rights.
Why a preservation project must avoid false authority
Open-source licences often allow particular forms of copying, distribution or adaptation, but the applicable licence must be checked for the relevant software and documentation. Project names and marks may also carry separate obligations. A commercial agency should not describe itself as the original author, official steward or security maintainer without evidence.
Likewise, recovering a decade-old package does not prove that it is secure or suitable for production use today. Historical code should be clearly labelled, and potential users directed to maintained upstream sources where they exist.
Frequently asked questions
Can you restore a project's old documentation without rebuilding the software?
Yes. Documentation preservation and software redevelopment are separate scopes. A historical reference site can be useful even if the underlying software is no longer maintained.
Can open-source materials always be republished freely?
No. Check the particular licences, attribution requirements, notices, trademarks and third-party material. “Open source” does not mean that every associated PDF, image or website design has identical terms.
Is it possible to keep old API documentation searchable?
Often, if suitable source files or authorised copies survive. Version labels, stable URLs, internal search and clear navigation are more valuable than merging incompatible versions into one undifferentiated archive.
Will restoring old documentation improve SEO?
It can make useful material accessible to people following existing references, but rankings and backlink value are not guaranteed. The priority should be a coherent resource that answers the original request.
Preserve a project before the knowledge disappears
If your organisation maintains an ageing developer site or has inherited undocumented software, contact TwoSquares with the project name, surviving repository or domain and the documentation most at risk. We can scope a practical recovery and publication plan.
