Used Textbooks.
I have slowly been making me way through a number of courses that I've found via iTunes. There are a number of Universities out there that have lectures up online and available for anyone to download. I've been taking the opportunity, since I've not been in school, to fill in gaps in my knowledge. I like learning things, so this is mostly fun, but sometimes its frustrating. It turns frustrating when you need to turn to texts in order to illuminate what a lecturer has said (or, in order to go deeper on a topic.) It becomes frustrating because there are a great many books out there that are not available in your average public library nor are still in print. This means going through alternate channels in order to procure these tomes so that you can read the relevant chapter or two (and then, more than likely put them back on the website from which they have come in order to make back what you just spent on them.)
It makes learning a little like a treasure hunt.
Sometimes, this is a funny process. It is hilarious the number of people who have books listed as being in "good" or "fair" condition that have higher asking prices than the people who say they have the book in near perfect or unused condition. However, it is less than hilarious when you see something listed for cheap and in "unused" condition, go to click on it and find that someone has, just then, beaten you to it.
