I have a web site where I post historic US Military documents (99% US Navy) that I find and scan in at the National Archives. I scan and OCR the originals but then have to proofread the final result to take out as many errors as possible ("attack pianos" versus "attack planes"). Naturally, having to carefully read each document multiple times gives me a much better understanding and retention than those that just skim them.
Likewise, some companies are having to re-think how they present information and make it accessible as younger generations are now assuming that if they can't find something, it's not that they haven't searched thoroughly, but that it's not there or doesn't exist. Having an instant search for everything is handy, but it can teach the wrong thing.
