I commented on Lorcan Dempsey’s blog about something I’ve been wanting to do for a year or so.
Allow someone to take a picture of an ISBN barcode that’s on most post-ISBN books, and send it to library software to get library services. Imagine if you could hold a book barcode up to your mac laptop camera (I have no idea how to write software that grabs such a picture), or snap a picture with your cellphone and MMS text it to a library number (I still don’t have a phone with a camera, but I think that kind of thing is possible?), and get a page like this (via Umlaut).
It’s not a trivial project, but it’s a feasible one, it’s definitely do-able. Anyone want to find the neccesary open source software and write the neccesary glue to create an open source package that will receive an ISBN snapshot, decode the isbn from the barcode, and send the ISBN to a link resolver? Good internship for a computer science student, yeah, come on, you know you want to.
