[Noughty]

They might already be on the shelves. Maybe even read shelf and I wouldn't know which ones I have read. Most of my books are already on Goodreads shelves, only small part isn't yet.

And putting on shelves looks more troublesome for the program, it always becomes unresponsive and is very slow.

And I thought it is better not to abuse the function to put on shelves? or no? After linking I download shelves, then see the ones which aint added and then view them on goodreads and add them on the webpage.
