Mike Beazley has published "Eprints Institutional Repository Software: A Review" in latest issue of Partnership: the Canadian Journal of Library and Information Practice and Research.
Here's an excerpt:
Setting up an institutional repository (IR) can be a daunting task. There are many software packages out there, some commercial, some open source, all of which offer different features and functionality. This article will provide some thoughts about one of these software packages: Eprints. Eprints is open-source, and the software is easy to modify. This presents clear advantages for institutions will smaller budgets and that have programmers on staff.
Installation and initial configuration are straightforward and once the IR is up and running, users can easily upload documents by filling out a simple web form. Eprints is an excellent choice for any institution looking to get an IR up and running quickly and easily, although it is less clear that an institution with an existing IR based on another software package should migrate to Eprints.
