Welcome to Librarybase, the collaborative card catalog of everything.

Librarybase is a project to organize, refine, and distribute metadata, as a complement to other projects like Wikidata or OpenAlex. The motivations behind the project are further described at Project:Principles.

Current projects

Classes and roles

Items are organized by class using Property:P19, with Item:Q410 as the root class item. The current list of classes is available at Special:WhatLinksHere/Item:Q410.

This differs from Wikidata's "instance of" and "subclass of" properties in that items are assigned classes according to a controlled vocabulary. This can be used instead of or in conjunction with those properties. One major departure from Wikidata is the concept of the single-edition work, used to avoid creating separate work and edition items when there is no real reason to.

One subclass is "role," which a member of a class can have. The current list of roles is available at Special:WhatLinksHere/Item:Q422.
