thingISBN agonistes
Tim Spalding, of LibraryThing renown, posted While You Were Sleeping, thingISBN Is Getting Better. thingISBN is LibraryThing’s equivalent to OCLC’s xISBN: give either one an ISBN and it will give you back a bunch of ISBNs that are other manifestations of the same work. thingISBN’s coverage and comprehensiveness is improving, as Spalding shows. It’s all done by LibraryThing users clumping things together, and it’s free.
