Your personal solution sounds interesting. I'd be interested to know more details about it, and how it works for you. If it is how I imagine it, it could also be one of those things that could be built into a tool that could rival Wikipedia or search engines. Based on your reply to handsomechad, you may think that it's easiest for people to just build one themselves. But there may be a business opportunity in providing a pre-packaged solution for the masses. In the same way that Dropbox provided a tool that was "trivial" to experts, but was difficult for non-experts (see the infamous comment here: https://news.ycombinator.com/item?id=9224 https://news.ycombinator.com/item?id=9224), if you have a tool that is essentially a rival to Google Books for reference texts, that is interesting.
