Got a big book collection and don't really want to take the time to catalogue the entire thing? If you snap a photo of your books into Evernote, it will create a searchable inventory for you automatically.

If you're an Evernote user, you're probably familiar with the free optical character recognition (OCR) it performs on any photos you save into a notebook. It doesn't need a picture of a text document to perform OCR -- just a picture with text in it.
Because the spines of all your books have the author and title on them, a photo is enough for Evernote to detect that information with its OCR. All you have to do is photograph your books clearly and save that picture into a notebook. By doing so, you'll be able to search for an author or title and Evernote will show you where that book is on your shelf.
