Though not all blogs may aspire to literary permanence, they can achieve it through the new Book-Smart software from Blurb, a publish-your-own-book service. The software, which is expected to be available free later this month at www.blurb.com, features a "Slurper" tool that automatically downloads and reformats the contents of a Web log into a book that bloggers and their admirers can purchase online.

Slurping is not all BookSmart has to offer. It simplifies the layout process by providing design templates for various kinds of books, including cookbooks, photo books, portfolios and volumes dedicated to pets and babies. The software guides users through design decisions like choosing text styles and how many photos will appear on each page.

Pricing for printed versions of your book from Blurb starts at $30 for an 8-by-10-inch full-color hardcover volume with dust jacket and up to 40 pages. A book of up to 80 pages is $3 more. (Blurb plans to eventually offer paperback editions selling for about 30 percent less than hardcover.) Authors will also be able to set up online bookstores through Blurb's Web site.

Although an early version of the software occasionally stuttered or froze, Blurb expects to have the kinks ironed out in time for its public release.
