How OER Texts Save Many $$$

This is an example of cross-mapping real world course syllabi to an open textbook, demonstrating that the open textbook covers all or most of the course content, thus permitting easy adoption and saving students thousands of dollars.

We compared Rutger University’s undergraduate Biology Course syllabi with our open biology textbooks. (See tables below). Rutger’s Bio 101 closely matches College Biology Vol 3 while their Bio 102 closely matches College Biology Vol 1.

Bio 101 & 102’s assigned textbook (Fall 2013) is Biology: Concepts & Investigations by M. Hoefnagels (2nd edition, 2011) Originally $225, now $39.51 used, rent $26.00 (

The current edition is Biology: Concepts & Investigations by M. Hoefnagels (3rd edition, 2011) $211. Rent $94. (

We’re convinced that the best choice is College Biology where the PDF is free and the print format per volume1 is only $39.20.

Why rent when you can own? Why pay 6 to 7 times more for the same content?

Depending up the next class-assigned textbook, saving range from $39.00 to $172 per student, which amounts to thousands of dollars per semester per college.

BTW – Textbook Equity’s Editors will customize any of our open textbooks to map to your class syllabus, create color textbooks, and add your own material. Output to PDF and print. (Example cross-mapping analysis below.)
