Not that I have a great collection, but each and every book on my shelf is precious to me. I don't know about you, but I have this habit of writing the events of the day and where I bought the book from on the inside pages of the books. So god-forbid if something was to happen to my collection, I would be totally shattered. Thankfully there are scanners in the market like the Booksnap book scanner from Atiz. It boasts to be the fastest scanner commercially available. It can scan 500 pages per hour. The flip side is (there is always a flip side!) that it doesn't include the actual scanning/ripping/picture-taking device; you need to get your own Canon cameras in order to make it work. Currently, the Booksnap is compatible with the Canon Powershot G7, Canon Powershot A640, Canon Powershot A620, Canon Powershot S80, and the Canon Powershot S3 IS.

Booksnap book scanner from Atiz comes for $1,595.

Hardware
Featuring a V-shaped book cradle, BookSnap allows for face-up scanning and keeps handling to a minimum, thereby reducing wear and tear on books. The cradle utilizes a unique auto-centering feature, which eliminates "margin crawl"
Software
A complete software package is included with BookSnap and completely automates the ripping process, making it as simple as the push of a button. In addition, the BookSnap Editor allows for post-ripping processing, including cropping, page resizing, brightness adjustment and DPI settings. In addition to PDF, BookSnap can output files to JPEG and TIFF formats.
