Since I keep getting asked why there are numbers at the end of the title folder name, the reason is for *robustness*. That number is the id number of the book record in the |app| database. The presence of the number allows you to have multiple records with the same title and author names. More importantly, it is part of what allows |app| to magically regenerate the database with all metadata if the database file gets corrupted. Given that |app|'s mission is to get you to stop storing metadata in filenames and stop using the filesystem to find things, the increased robustness afforded by the id numbers is well worth the uglier folder names.
Finally, if you are irrevocably wedded to the filesystem, feel free to patch your local copy of |app| to use whatever storage scheme you like. But, do not bother me with requests to change the directory structure, **they will be ignored**.

This allows you to use the search features to limit the books to be catalogued. In addition, if you select multiple books using the mouse,
only those books will be added to the catalog. If you generate the catalog in an ebook format such as EPUB or MOBI,
the next time you connect your ebook reader the catalog will be automatically sent to the device.
