HI Charles, Thanks for the response.
Does anyone know what the ebooks field is supposed to return? What do the various parameters mean? I'll play around with it. I am also checking if my mail got through to the tech list. - Nilanjan ------------------ Revelutions Counterfactuals Date: Wed, 1 Oct 2014 16:26:05 +1300 From: [email protected] To: [email protected] Subject: Re: [ol-discuss] finding if a book has an ebook (API) Hi Nilanjan, First off, I'm on the ol-tech list too, and I haven't seen this question before. Hope no one minds me answering the question here, as this is where I've seen it.

I wonder if someone here can help. I want to figure out if a book has a ebook on openlibrary. Take a look at this: https://openlibrary.org/works/OL1940521W/Testing_computer_software The subjects show me 'In library' - I assume that means there is an ebook. I don't know about the subject 'in library' -- it doesn't sound like a reliable way to determine if a book has an e-book. Clicking on the subject gives a list of "241,107 works / 239,752 ebooks" so it doesn't look like a valid conclusion to draw. The subject field should be the subject of the work, these look like bad / misplaced data to me. Maybe someone else knows what this is about. However, when I go to the actual book I don't see the 'subjects' field. When I use the API I get the same behavior, i.e,. for the OL1940521W record I see 'subjects', but not for OL1737246M Can you help me make sense of this? I have had a look at the book in question and how it shows up in the ruby gem, what I think you want to see is the 'ebooks' field as documented in the books API https://openlibrary.org/dev/docs/api/books The API request for the book you mentioned is https://openlibrary.org/api/books?bibkeys=OLID:OL1737246M&jscmd=data which has the "ebooks" field there:"ebooks": [{"formats": {"djvu": {"url": "https://archive.org/download/testingcomputers00kane/testingcomputers00kane.djvu";, "permission": "restricted"}}, "preview_url": "https://archive.org/details/testingcomputers00kane";, "availability": "restricted"}]I was about to tell you the ruby Gem doesn't support this field, but thats not true... You won't be able to see the ebooks if you use the Rest Client, which is what I assume you tried first. You'll need to use the Books Client / Openlibrary::Data :data = Openlibrary::Data book = data.find_by_olid('OL1737246M')book.ebooks => [{"formats"=>{"djvu"=>{"url"=>"https://archive.org/download/testingcomputers00kane/testingcomputers00kane.djvu";, "permission"=>"restricted"}}, "preview_url"=>"https://archive.org/details/testingcomputers00kane";, "availability"=>"restricted"}] Hope that answers your question!
