Open Text Books or Open Educational Resources (OERs):
OER's are "learning, teaching and research materials in any format and medium that reside in the public domain or are under copyright that have been released under an open license, that permit no-cost access, re-use, re-purpose, adaptation and redistribution by others" (cited from UNESCO).
They are a good alternative to textbooks because they are freely available online. Check authority by looking at the qualifications of the authors or whether the titles are peer-reviewed.
