I'm lucky enough to be using Archivists' Toolkit (AT) at my internship with the Atlanta University Center. AT is an open source archival data management system that allows archivists (or graduate interns) to enter the finding aid data for a collection without knowing how to code EAD.
Being a curious person, and a glutton for punishment, I thought I'd try to install and use AT on my Windows Vista laptop and connect to a test MySQL database in my shared web hosting account (at bluehost). I discovered a few gotchas and have, I hope, explained the installation process in a clear, linear way that will help others perform this installation more quickly. Mind you, I came to the realization that AT currently doesn't work on Vista, but the steps are the same for XP.
