These links will take you directly to the portions of databases that contain materials relevant to Biology. However, this is by no means an exhaustive list. Feel free to explore the General Collections to find additional resources.
All the materials in MERLOT are reviewed for suitability for retention in the collection. Many undergo the more extensive "peer review" for which MERLOT is famous. As described in Material Link Checking and Removal, all material URL's in the collection are reviewed frequently for sustainability.
Hippocampus offers educators a wide variety of multimedia content online, including videos, animations, and simulations. An additional feature offers educators the ability to create "playlists" for their students, which correlate specifically to their particular instruction material.
The LibreTexts approach is highly collaborative where an Open Access textbook environment is under constant revision by students, faculty, and outside experts to supplant conventional paper-based books.
Pressbooks supports blended and online learning with an intuitive authoring platform for educational material, an extensive directory of public books and open educational resources (OER), and secure methods of delivering content to learning management systems (LMS). Create or import content, add multimedia and interactive elements like quizzes, integrate content into the LMS, deliver content online and in multiple downloadable formats, and assess and track student learning—all with one easy-to-use platform.
