I created a demonstration project for the Raspberry Pi computer to provide a sort of ‘Library Service’ as a website. You can upload a bunch og JPG files that should be scans of book pages, and the site will decompress those JPGs, OCR the text data, and store the results as book that can be read and text-searched online.
It uses all open-source such as Apache, PHP, MySQL, tesseract, and Internet Archive Book Reader. I laid out a more detailed description of the development at http://www.librarypi.com.
The source code is available on github: https://github.com/MarioGiannini/LibraryPi
At the time, this was an interesting project because of how it utilized something as small as a Raspberry Pi for a web server, combined with scanning and archiving which was a decent portion of my work at the time.
