Publisher:Many Books

Many Books is a republisher of Project Gutenberg releases. Many Books provides the items they choose to republish in over 20 different formats.

Many Books graciously provided the ISFDB with it's own search form in order to reveal the Many Books publication date, which is hidden from normal users. (Most users just want to know when it was first published in print form, not ebook form).

The interface is available at
