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
Historic patents
An effort to build a unified database of historical patents. Data coming eventually.
Odia Bibhaba
Books written in the Odia language. Data pending import; demonstration item
Copyright expiry
Metadata items were created on works that may or may not be in the public domain, facilitating identification of these works. Example item
Classes and roles
Items are organized by class using Property:P19, with Item:Q410 as the root class item. See current list of class items on Librarybase Query Service. This is meant to bring Librarybase closer in alignment with databases like Fatcat and OpenAlex.
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. See current list of role-type items on Librarybase Query Service.
