In that case, let's turn this question into a feature request: either a method to get user data for a given book, or, even better, implement what I was planning on implementing via this method: statistics for each book, such as the average time it took users to read it (e.g. median of [date finished] - [date started], for valid dates), and perhaps a ranking of books based on this metric.
Thanks for the great site!

Is there any method or combination of methods in the API that will allow me, given some book (title, or ISBN, or id, or whatever is necessary) to get the "date started" and "date finished" fields for each user who has read it?
Thank you in advance!
