In the previous post, I mentioned public libraries. Public libraries are definitely in the "good enough" category as I've defined it. Where else can you get access to all of those resources for free? Not to mention the help of the librarians. I don't know about every town of course but in our town it's worth it to memorize the number of the reference desk at the library. Any time you have a tough question, try calling a librarian - they know where and how to find some of the most obscure answers out there. They're the unsung heroes of the information age!
