Print ONE custom book containing Wikipedia articles of your choosing. Starting at $8.90 (100 pages). Book is printed the next day by publish-on-demand process. It is a commercial quality paper back made by the same manufacturer that produces most trade books today.

The Create a Book feature from Wikipedia enables a user to build a custom book from the articles chosen from their search on Wikipedia and other wiki sites that are supported by PediaPress’ book creator feature. Illustrations and photos from the articles are included also. Upon the completion of content collection, the user creates a book title, adds an editor name and selects a cover photo from a group of images and photos associated with the content selected. A 30-page preview is provided to the user for review. The user purchases the book online from the pediapress.com web site, and book files are then uploaded for manufacturing. Printed books are then shipped to you from the closest of the networked print facilities.
