Often I find that very good resources are sitting right under my nose, and I just haven't noticed them yet. I work at Georgia State University as a Software Systems Engineer. We basically run servers for various projects across the University. One of these projects is The New Georgia Encyclopedia. I'd never really looked at the content of the web site, even though we host it.
Early this morning I did a web search on Joel Hurt, the developer of Inman Park and Druid Hills in Atlanta. One of the listings in the search was to the New Georgia Encyclopedia. Not only did the NGE have a very informative page on Hurt, but it included pages on an amazing variety of topics of interest to me, including the Savannah city plan , Lemuel P. Grant and the Grant Park neighborhood , and many other topics of interest to me. If you are looking for information on any topic related to Georgia or a city in Georgia, it's a good starting point.
