Libraries 

When I really ran out of money, I discovered the libraries. I'd always detested them, especially after they said you couldn't smoke there anymore, since I'm sort of a chain smoker.  But here are some cool options for getting books for free.  And I also had finally come to realize that it was okay to throw away about 80% of the books I owned, because I'd been collecting them for decades, and because really most of them were just like old magazines, periodicals, good for a season, but then best thrown away than moved in boxes everywhere you go for the rest of your life.  Just keep the reference stuff, dictionaries, atlases, the very things they won't let you check out at the library. Have you really given any thought to how useless a 30 year old psychology textbook is going to actually be?  If you are a student or faculty member at Georgia Perimeter College, you can use the same libraries I do.

Atlanta-Fulton County Public Library 
If you live in Atlanta or Fulton County, you should get your free library card.  They will mail it to your Atlanta or Fulton County address to make sure you're actually there where you said you are.  Otherwise, you can pay them something like $50 to get one, though you'll probably save this much with the first few books or CD's you borrow.  They've got way more stuff than I imagined, many things you can't find at the local academic libraries, especially since the GSU Pullen Library decided to not take the moral risk of allowing us GPC people CD's and videos.   etc.  You can search their entire system, which will include all branches, for what you want. And then when you find it, you can tell them online where you want to pick it up, at which branch, and they'll deliver it there and notify you when it arrives there in a day or two.   So, if you just live near the Dork Branch Library, which does not have much on its shelves, or doesn't have what you want on its shelves, you can just use that as your pick-up spot; it's like how the old Sears Catalog Stores used to work.  The internet has changed everything about how to use the Atlanta-Fulton County Library. But, please be resectful of their collection; don't write in the books or otherwise damage their stuff, the public's stuff, your stuff, and please always return it; it's a good way to encourage other smart people who think like you think to get the materials that please you pleasing them, making more like-minded people for you to talk to around somewhere. 

Georgia Perimeter College
You know the place.  But don't forget that you can find something online and have them deliver it to your campus library, where you can swing by and just pick it up, as with the Atlanta-Fulton County library branches.  This is not at all like an inter-library loan, with all those limitations, such as that you might only be able to keep it for a few days before they have to rush it back to its owners.  It's just a regular library asset like any of the others at your campus's branch of the library, and you can just return it where you picked it up; it's just a shelving thing for the library.

Georgia State University - Pullen Library 
You can use this the same as the GPC libraries, though, as noted above, they won't let you check out books and videos.  They've got an excellent book collection, far superior to GPC's. So, if you can't find it at GPC, then click on the link here, and if you find what you want GSU, then just go there and get it!  Don't be shy; you're already paying for it; so use it!

The Teaching Company (1-800-832-2412 = 1-800-TEACH12)
These people have some excellent courses on audio and video, in several formats.  They are college-level lecture series of from 16 to 48 lectures each. Really, it's better than it sounds, though the materials are of uneven quality. I haven't found any of the philosphy courses to be what I would consider good, and the logic course I got from them was downright awful. But the history, religion, music and science courses are particularly excellent. The course I got on the Reformation was pretty bad, actually boring and I thought poorly organized. But the courses on Ancient Greece and Rome by McInerny, Fagan and Fears are all excellent. Also, the music courses by Greenberg are excellent, though they require some serious hours of attention both to his lectures and to listening to CD's you'll need to get separetely of the musical pieces he discusses. I would especially recommend the series on the Beethoven Symphonies and the large overview How to Listen to and Understand Great Music. Also, Great World Religions, as well as some of the Old and New Testament courses gave me a general grounding in religion I was previously lacking, and I'd recommend it to anyone. You can fill a lot of gaps in your general education with these Teaching Company courses.  So, call them and tell them to send you a catalog. If you purchase, they will put you on their regular mailing list, and you'll be astounded at what they offer. However, be sure to order courses only when they're on sale.  They do this on something of a rotation; so, if a course is not on sale, wait a month or two and it will be on sale. They do this for economies of scale in production. And the savings are sufficient to make it absurd to order at their "regular price," since the sale price is usually about 1/3rd of this "regular price," and they all go on sale within a few months in rotation, and I think some are actually usually on sale.
