Well, I finally have the first portion of our collections online. PastPerfect was very easy to use to accomplish this. There are still a couple of little things that I need to add as far as a statement that our library holdings are non-circulating, but other than that it's done until the next additions in December (we're adding collections every 6 months). The people at PastPerfect were very helpful with the couple of questions that I had, and I found the entire process of uploading to be very user friendly. If anyone is considering using PastPerfect online, I'd be happy to speak with them about my experience.
Oh yeah, here's the link to the fruits of my labor
