We're coming with a spreadsheet of quotes within a book that takes place at particular locations in Manhattan, their latitude and longitude, and several other categories of information, such as genre, author, etc.
We'd like to build an app on the foursquare API, that let's users "check out" their favorite author, genre, etc. and then receive emails with the quotes when they approach locations that fit their criteria. That way they can actually read the quote while they're on location and have the meaning transformed by seeing the things as they read about them.
The quotes will then link back to the publishers' webpage or another place they can buy the books.
We really believe in this idea and already have a platform we can use to get it in the public's eye.
Let me know if any of this is unclear, or if you have further questions.
