Here is another piece of open source software solution "for showcasing, teaching, and archiving popular print and countless other kinds of collections and artifacts." Streetprint Engine was developed at the University of Alberta to solve a specific problem. Now the software and documentation are available to anyone. The web site links to some collection that use it and contains a forum where people discuss the software.
digitizationblog did a review of Streetprint Engine back in August and said that the software was easy to use, but had some rough spots. If you're looking for software to "power" a digital collection and you're agreeable to using open source software, be sure to give this one a look.
