Annie, at the Same River Twice, writes a nice blog. Today she writes about sneaking into college bookstores to see what the kids have been assigned - always good fun. In fact, I often chose my fourth undergrad class that way - pick the books then worry about the time and the professor.

Her comments don't work, so here is my reply to her:

You can also surf college textbooks virtually, although without the pleasure of running your fingers over the books and opening them to read a few paragraphs from the middle.

Search for syllabi - most colleges have some of them on line.
Then check the catalog for your local library to see which of the interesting books are available. I do a lot of my book browsing that way - with an amazon or a google window open on the left and the library catalog open on the right.

ps, email if you want a reading list (grin)
