JISC-PoWR has released the Preservation of Web Resources Handbook.
Here's an excerpt:
The Handbook is structured in two parts. The first part deals with web resources and makes practical suggestions for their management, capture, selection, appraisal and preservation. It includes observations on web content management systems, and a list of available tools for performing web capture. It concludes with a discussion of Web 2.0 issues, and a range of related case studies. The second part is more focussed on web resources within an Institution. It offers advice about institutional drivers and policies for web archiving, along with suggestions for effecting a change within an organisation; one such approach is the adoption of Information Lifecycle Management. There are separate Appendices covering Legal guidance (written by Jordan Hatcher) and records management.
The Handbook also contains a bibliography and a glossary of terms. The Handbook is aimed at an audience of information managers, asset managers, webmasters, IT specialists, system administrators, records managers, and archivists.
