SPARQL endpoints for library catalog data or other metadata?

I've found the following SPARQL endpoints for library-related data:

Library of Congress of Chile: endpoint here
OCLC's dewey.info: endpoint here

Surely there must be more endpoints out there, for catalog data, other library metadata, and library vocabularies than this? Where else should I be looking?

The Data Hub seems to be a good starting point for datasets with SPARQL endpoints. There is a group of datasets called "Bibliographic data".

http://thedatahub.org/group/bibliographic?res_format=api%2Fsparql gives the datasets in that group, but only the ones with a SPARQL endpoint.

This is listed on the Data Hub site, but is worth calling special attention to.

The British National Bibliography is available via a number of APIs, including SPARQL. These APIS are documented here.

The URL for the endpoint is bnb.data.bl.uk/sparql .

The German National Bibliography is available as RDF, but is not currently front-ended by a SPARQL endpoint. I suspect they probably have a few pilot endpoints running internally. The DNB are available, but with search only via SRU and OAI-PMH at the moment, but since you can bulk download, you can make your own endpoint.

dsalo: Heh, making my own endpoint is more work than I'm prepared to do for my simple purposes. I just want to work up a SPARQL exercise or three for late in my databases/SQL-for-future-librarians course. For that I need endpoints!

Cambridge has an endpoint here for a partial snapshot of its data.

We've also added a tutorial to SPARQL based around bib data and the endpoint.

dsalo: Yay tutorial! Bookmarked, thanks; that makes it a lot easier to plan a lesson.
