About self-publishing, who do you recommend, and why? How about Blurb.com?
As you can imagine, this is a topic that comes up with some frequency, but I think there's a hidden question behind this question. The term "publishing" creates a lot of confusion and obfuscation. By that, I mean to clarify that publishing is an entirely different thing than "producing and printing."
Getting your work in print is far easier than getting your printed device distributed into the world. In the traditional sense of the word, publishing involved a number of tasks including: editorial work, layout and design, printing and binding, marketing and advertising, inventory storage, distribution and fulfillment, and remaindering. When photographers asked me about publishing their work, they typically are not thinking about all these disparate tasks.
More often, they're concerned about layout and design and printing only — and the eventual use of what to do with all those printed books never comes to mind. This is precisely why so many photographers have piles of commercially printed books in their basement or garage — and no idea how to get them into the hands of consumers. Anyone with a large enough checkbook can get a book of their work printed, but getting it distributed is an entirely different task.
So, to answer Myron's question with a bit more specificity, self-publishing is a difficult road unless you already have a market for your work — workshop students, a well-established website, etc. I don't recommend it for the faint of heart.
As to printing your work in a Blurb.com book, the general consensus is that they do a fine job if your standards are modest. The critical photographer with a keen eye will likely be disappointed when comparing a Blurb.com book to a commercially printed museum-quality art book. This is especially true with black-and-white work. Test it, but keep your expectations in check until you see the results. Even then, don't be surprised if a run of books exhibit variations and color shifts. It's the nature of the print-on-demand technology that produces these kinds of publications.
