Published by the Research Information Network in January was this report, E-journals: their use, value and impact: final report "This two-part report takes in-depth look at how researchers in the UK use electronic journals, the value they bring to universities and research institutions and the contribution they make to research productivity, quality and outcomes." As well as the reports from phase one and two, there are working papers on journal spending, use and research outcomes, on bibliometric indicators, on citation practice, and on information usage and seeking behaviour.
Researchers are accessing journals a lot via gateways (e.g. Google or PubMed) and tend not to use advanced search. There are disciplinary variations in e-journal use. A lot of e-journal use takes place at evenings and weekends. Also "UK researchers are producing more articles, with more references, from a wider range of sources than they were two decades ago."
