Public Domain Archive and Reprints Service is “an experimental non-commercial project to archive and re-publish public domain works.”

Let’s say you’re going through the more than half-a-million public-domain books available as PDFs at Google Books and the Internet Archive, and - being from the old school - you think how great it would be to have a certain rare old book in actual book form: a printed, bound, softcover object you can hold. This service lets you do that. They say the price ranges from $5 to $19.

[ADDED:] Almost 4 million different titles can be printed this way.
