There is no limit to the total number of books (i.e., links to books) you can save to your bookshelf.
However, only about 1,000 books can be at any one level. If you have more than that at a single level, you may start to lose information from the last titles in the list.
The solution is to nest the books in your bookshelf into folders. You could, for example, create subject folders or alphabet folders (e.g., folder “A-C” for all titles that begin with one of those letters). To create a folder, simply go to the Bookshelf and click on New Folder as shown below.
In summary, it is important to put your books into folders so you never have more than 1,000 at any single level.
