Obtain rating of a book

Hi,

I want to write a small application for the Nokia n810, that allows me to search the rating of a book in librarything. Some times i am in a bookstore, see a book and want to know the score in librarything. To do this with the browser, i need to load the main page, search the book and choose the title from a list... a lot of steps and very long with a telephone connection.

I think the easiest solution is to request the ISBN from the user (in the library you can read it in the book) and get the score from librarything. Is there any way to retrieve this information? I cannot find the proper method in the API. should i take the page of the book and parse the HTML?

Thanks,

Ivan

You can do it with the JSON works API and some static HTML:
