Check out Blurb.com
if you have ever wanted to self-publish a catalog of your work, or any other kind of book. This is an amazing website that allows you to do just that, using their free software. You design your book page by page using a large array of available templates and options for design aspects. It's really easy to understand and to view as you progress.
When you're done, you can order any number of copies at very reasonable prices (starting at $12.95 for one 20 page copy, plus S/H.) If you think anyone would pay money for it, you can even sell your book from their website without any upfront cost--they print as orders are placed.

A person could go nuts with this. For now I'm sticking to art topics--with plenty of ideas spinning out from there. For example I could see making one "serious" or "professional" catalog for the galleries, and another one that was more personal or autobiographical. You can even import blog posts into book format with this software...
