The Distributed Proofreaders project continues to have a very productive November, with yet another Project Gutenberg release today derived from our Digital Library images.

Today’s release is an issue of the Instructor Literature Series, a set of thin booklets used as “graded readers” for educational purposes in the early 20th century. This volume, no. 256 in the series, is Katherine Atherton Grimes‘ Bolo the Cave Boy, which describes life in prehistoric times, imagining how cave people hunted mammoths, dealt with natural disasters, shared fire, and began to develop agriculture.

If you’d like to read the whole book, you can find it freely available for online reading or download in popular eBook formats at Project Gutenberg.
