Harvard University’s 12 million records now in LibraryThing « The LibraryThing Blog

“On April 24 the Harvard Library announced that more than 12 million MARC records from across its 73 libraries would be made available under the library’s Open Metadata policy and a Creative Commons 0 public domain license. The announcement stunned the library world, because Harvard went against the wishes of the shared-cataloging company OCLC, who have long sought to prevent libraries from releasing records in this way. (For background on OCLC’s efforts see past blog posts.)  It took a while to process, but we’ve finally completed adding all 12.3 million MARC records (3.1GB of bibliographic goodness!) to LibraryThing. They’ve gone into OverCat, our giant index of library records from around the world—now numbering more than 51 million records! As a result, when searching OverCat under ‘Add books,’ you’ll now see results ‘from Harvard OpenMetadata.’
