All thingISBN data available in one huge file
LibraryThing has done something very useful and generous. As you know, Bob, their thingISBN service is akin to OCLC’s xISBN: give it the ISBN of a book and it will return a list of ISBNs of other editions of the same book. In FRBR terms, we say: give it the ISBN of a manifestation and it will give you a list of ISBNs of manifestations of the same work.
Tim Spalding says in thingISBN Data in One File:
APIs, while nifty, can be a pain. Both thingISBN and xISBN have a 1,000-per-day limit. So, starting today, thingISBN is also available in feed format—one giant XML file with all the data from over two million unique ISBNs.
He doesn’t give a direct link to the full file, probably because it’s 16 MB in size and search engine crawlers would go at it relentlessly, but all you have to do is look for where he gives the URL in plain text. He even gives some sample SQL to help get the stuff into a database. Download it, fool around with it, find new uses for it! Good for LibraryThing.
