The JISC project on Preservation of Web Resources (JISC-PoWR) project, of which I’ve contributed some of the legal work, has just released v1.0 of the Handbook at: . A DOI or URI will likely be on its way, but until then you can always get the latest version at that URL.
I’m really pleased with the way the JISC-PoWR Handbook has turned out and had a great time participating in the project. Thanks to Marieke, Ed, Richard, Brian, and Kevin for all their hard work and for including me in the project team. There are lots of plans for continuing the work started here, so be sure and stay tuned to the JISC-PoWR blog for more information.
