For the organizationally-inclined among my readers, I have a favor to ask.

What I need is a system, or a piece of software that will help me keep track of publicity mailings–basically, where I sent what.  I’ve been using an excel spreadsheet to keep track, but it’s not ideal. I’d like to have something that will cross-reference all my data, so I can look at a book and see where it’s been sent, look at a review venue and see what I’ve sent them, and look at who actually reviewed what.
