"... How about scanner and OCR? ..."

I was thinking of school books & standing in the line for photocopiers for reference books in the library.

My graduate university kept a good number of copies of required texts in the library that could be lent out for the length of the course. Reserved copies (i.e., can't be taken out of the reserved area) were available as well. No student had to buy any books unless they wanted to.

I think that's my favorite system.
