What is Wikisource and what kind of content does it host?

Wikisource is a free online library that anyone can improve, and it hosts source texts rather than encyclopedia articles. The main Wikisource site at wikisource.org is the multilingual hub: it holds works that don't fit a single language edition, and it connects the separate language-specific Wikisource projects. Use it when you need a primary text (a book, document, or transcript) rather than a summary of one.

What kind of content lives on wikisource.org

The multilingual site is explicitly a home for works that the language subdomains can't or won't take. According to the site's main page, works hosted there include:

• Works in multiple languages — texts that mix or parallel several languages and therefore don't belong to one language edition.
• Works in languages without their own subdomain — for example, languages with a small corpus that hasn't met the threshold for a separate project.
• Works made up of non-linguistic content — material that isn't primarily running text.
• Works excluded by a language site's own policies — languages that do have a subdomain, but whose local rules prevent hosting a particular work, can still place it on the multilingual site.

That last point is the practical one for readers: if you can't find a text on, say, the English or French Wikisource, the multilingual site is a legitimate second place to look.

How the language editions are organized

The main page groups language projects by how many works they hold, which is a quick way to judge whether a language edition is likely to have what you need:

A larger tier generally means a deeper catalog, but it says nothing about whether one specific title is present — check the edition itself.

Deciding whether Wikisource is the right source

• Choose Wikisource when you want the text itself: a novel, speech, treaty, or historical document, ideally with a scan or source behind it, and you want to read, quote, or verify the wording.
• Choose Wikipedia instead when you want context, summary, or analysis of a work rather than its text.
• Choose the language-specific edition when the work is in one language and that edition exists; the multilingual site is the fallback, not the default.
• Expect community editing. The site describes itself as a library "anyone can improve," so texts are transcribed and corrected by volunteers. For citation-grade accuracy, compare against the linked scan or source when one is available.

A concrete case: if you need a public-domain novel in English, go to the English Wikisource (in the 100,000+ tier). If you need a short text in a language with only a few dozen works, or a document that switches between two languages, start at wikisource.org and use its language listings to find the right project.
