Thanks Karen.. That does help, since I’m completely new here. Basically, I guess the question is if given only a ‘W’ Works key how do I get to the Edition or ‘M’ key. It looks like all the works have a unique ‘W’ key, so there should be a way.
As a little more of background: I extracted a dump, which gives me a lot OLID’s that end in ‘W’ that I can use on the web. For example: https://openlibrary.org/works/OL15346679W.json works and gives me this: {"title": "Adventures of Tom Sawyer", "created": {"type": "/type/datetime", "value": "2010-08-20T09:50:50.944421"}, "last_modified": {"type": "/type/datetime", "value": "2012-07-07T03:04:45.302947"}, "latest_revision": 2, "key": "/works/OL15346679W", "authors": [{"type": {"key": "/type/author_role"}, "author": {"key": "/authors/OL18319A"}}], "type": {"key": "/type/work"}, "revision": 2} But the info I need is in an edition so, I need a key that ends in ‘M’ so I’m having trouble finding books. No results are returned with OLIDs that end in ‘W’. Example this works: https://openlibrary.org/api/books?bibkeys=OLID:OL15346679M var _OLBookInfo = {"OLID:OL15346679M": {"bib_key": "OLID:OL15346679M", "preview": "noview", "preview_url": "https://openlibrary.org/books/OL15346679M/Raghuvam\u015ba_cantos_14_15.";, "info_url": "https://openlibrary.org/books/OL15346679M/Raghuvam\u015ba_cantos_14_15."}}; but this yields nothing: https://openlibrary.org/api/books?bibkeys=OLID:OL15346679W var _OLBookInfo = {}; I’m puzzled. t Thanks.
