When considering textbooks for your courses, you might take a look resources offered by the Community College Consortium for Open Educational Resources. The goal of the consortium is for educators to pool their expertise to create resources for community college students and faculty.
Community College Open Textbook Collaborative offers a growing selection of subjects suitable for community colleges. Textbooks submitted must follow guidelines regarding copyright, formatting and accessibility. Textbooks are peer-reviewed; the Peer Reviews section will identify the results of reviews. Books are rated for clarity and comprehension, readability, consistency, appropriateness, interface, content usefulness, modularity, errors, reading level, and cultural relevance.
If you would like to get involved with the College Open Textbooks Professional Network, consider joining the forum or piloting textbooks.
