ResourceSpace – Free and Open Source Digital Asset Management (DAM)
http://www.resourcespace.org/

ResourceSpace is a web-based, open source digital asset management system which has been designed to give your content creators easy and fast access to print and web ready assets. Features include: 1) Your users serve themselves so your internal workload is reduced; 2) Resources are found easily and quickly; 3) You can respond faster to external resource requests; 4) It’s much easier to send your resources to those that need them without using up your own bandwidth: suppliers receive links via e-mail so they can download the resources themselves directly from the system; 5) Higher quality resources are promoted so use of your best resources is encouraged; 6) A centralised and well organised repository encourages the re-use of purchased resources; 7) Only a web browser is needed – no cumbersome client software installations; 8) Collaboration is encouraged through the use of shared resource collections and searches; and 9) Discover and respond to trends by using the detailed reporting and statistics functionality. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
