The ResCarta Foundation has been assisting libraries in Wisconsin to collect, index and display culturally important local materials.
We call them ScanDays. The foundation provides scanning equipment, digtial cameras, software and training. The local library provides marketing, the space to hold the event and volunteers to man the scanners.
You can pick a link to the resulting websites from the days held so far on the right side of this page.
Here is a link to the handout for a presentation we made at Internet Librarian 2011 on the subject. ScanDays.pdf
