Two things I like:
1. Free
2. College students not paying high prices for textbooks. Remember the post here about discount textbooks options? I prefer low price textbooks that are high quality.
Oh, let's add a third thing I like....Boundless textbooks! The are free, appear to be high-quality, and look at all the disciplines they serve.
College students, before you purchase another textbook, check with your instructor to see if you can use a free Boundless text instead.
I'd love to know what you think of Boundless when you do.
