Description:
BookPrep is a web service that allows book publishers/content owners to bring back all their out of print books. Through our web site consumers can search our collection, read these books online, and order printed copies. The BookPrep service is designed to prepare scanned books for the Print on Demand (POD) market as well as for online consumption.
BookPrep takes raw scanned images and cleans up artifacts that exist due to age or that are introduced during the scanning process. The processed pages are then packaged into various formats for both print and online distribution. Once the artifacts are cleaned up, we package the book pages into various forms for printing and online consumption. In cases where original scans of the book covers are not available, publishers can design their own covers and integrate them into our cover generation system. We include a rich set of predefined cover templates for this purpose.
