I built my own Digital Library in 2006-2008 for Graduate School. It was very handy and I could have the books read to me in PDF while driving and search the text for research. Took about 30 minutes per hundred pages and I did it for HOURS. In Theology (Historical was my specific discipline) it was common for each class to be from 3,000 pages to 12,000 of reading (Yes a thousand pages a week basically for one class) I had to pick and choice which text was necessary and historically many of the books were public domain and I could download and grep them. I would have cut off my left hand for this device. I bought a book scanner for this and it was worth it to me. The OCR was fairly weak but it was okay at the time.
