Pull quote: "By now, though, there’s been a definite shift towards wider and more common opening up of bibliographic records. Large libraries like the German National Library and Harvard have released millions of the MARC records into the public domain. OCLC has revised its data policies to give their blessing to member libraries releasing their catalog data under ODC-BY. (They’ve also released some of their own data sets, like VIAF, under that license.) And large online library collaborations like Europeana and the Digital Public Library of America have adopted a policy of public domain status (using the CC0 declaration) for their bibliographic metadata. Both of these projects are now supplying promising platforms for projects that can aggregate, reuse, and build on this data in interesting and useful ways."
