Yeah, I could ditto this. 🙂 Had written something based on this plugin a few years ago and realized it’s very slow for building a large page full of books. Had some discussion on the open library mailing list. I think there’s a better API to use… might followup someday. :)… in the meantime caching would be really useful.
Update: just realized he’s using the new API now 🙂 Still caching would be good.
Hi, have you seen the new “HTML” option. When you are in Visual Editor mode, you will see a new OpenBook button that pops up a screen with an HTML option. Using this method, only you make one live api call to Open Library when you generate the HTML; the HTML gets inserted in the post. For the reader, there is no api call, so it loads as quickly as HTML. Works much better for pages/posts with many books. Note: the cover image itself is still loaded remotely but using an img tag which loads fast, not like the api call.
A minor update is expected for OpenBook soon, but caching is not on the list. My attention is currently focused on the development of a new concept, an OpenBookShelf, one that works more like the Media Gallery in WordPress. It represents a better overall approach to managing book data, including remote load issues. It will take some time before it is ready. Collaboration is invited.
