Here's an excerpt:
This report is an effort to begin to synthesize the evidence available under the JISC digitisation and eContent programmes to better understand the patterns of usage of digitised collections in research and teaching, in the UK and beyond. JISC has invested heavily in eContent and digitisation, funding dozens of projects of varying size since 2004. However, until recently, the value of these efforts has been mostly either taken as given, or asserted via anecdote. By drawing on evidence of the various impacts of twelve digitised resources, we can begin to build a base of evidence that moves beyond anecdotal evidence to a more empirically-based understanding on a variety of impacts that have been measured by qualitative and quantitative methods.
