Out of curiosity. Where does the metadata for the books come from?

Cool! I used to use goodreads and have been looking for another way to organize my digital bookshelf.

Some UI/UX feedback since you mentioned it:

- The bounding box for the books is large enough that I can trigger the popup of a book on shelf row-1 from current row.

Where do the covers come from?

I miss Delicious Monster's Library app

Is it possible to import Goodreads history?

Wow, the shelf UI is a real throwback to the old iBooks shelf design! Looks great. +1 on the bounding box issue, it takes me out of the flow when accidentally triggering a book below the current shelf.

I have completely lost track of what I have read and my thoughts. I really should journal. That being said as somebody else mentioned this is very pleasing to the eye. The UI with no ads and no buy buttons is so refreshing. I see that some of the covers are from specific editions. Any way to change those? Where are they coming from? I will give it a try and add a few books and see. Good job!
