Via Timothy Chow blogging at Terence Tao’s blog, I learned about outofprintmath, a kind of survey site for people to express their desire to have out of print math books brought back into print. One of the classic texts of information theory by Csiszár and Körner has been out of print for a while. Many grad students have been frustrated its unavailability (even the library copy is often checked out nearly permanently). There are (illegal) ways around this, but a photocopied book is just not the same as a real one you can take to a cafe and read.

Bobak (I think) has added Csiszár and Körner to outofprintmath. It’s number 51. Go vote!
