Great paper in D-Lib about personal digital libraries by Neil Beagrie.

People are capturing and storing an ever-increasing amount of digital information about or for themselves, including emails, documents, articles, portfolios of work, digital images, and audio and video recordings. Computer processing, storage, and software tools available to individuals are increasing in power, volume, and ease of use, year on year. Many issues arise from this more informal and increasingly empowered landscape of personal collection, dissemination, and digital memory, which will have major future impacts. This article provides a commentary on current research and emerging services in this area and discusses potential implications for individuals, libraries and their institutions.
