E-journals: their use, value and impact
Key findingsE-journals are a big deal
E-journals are the life-blood of UK research institutionsIt is now estimated that 96.1 per cent of journal titles in science, technology and medicineare available online
Nearly everything made available is used
Information seeking is fast and direct – researchers use gateway sites
Usage is rising and cost-per-use is falling
High levels of expenditure are associated with high levels of use
- Research Information Network

“During the recession there was a reduction in cost for most commodities and goods—with the Consumer Price Index (CPI) dropping in 2009 and only increasing 1.6 percent in 2010. During that same period, serials prices continued to rise at well above the CPI (four to five percent), and, against the backdrop of decreased funding for libraries, price increases are very hard to sustain. Libraries do not have the resources to continue to exist in a world of ever-increasing prices, nor can publishers exist in world of no revenue increases.”
