This article by Stuart Stone, Librarian at the Radzinowicz Library at the Institute of Criminology at Cambridge, examines a selection of online information resources used by criminologists and compares their particular features and deficiencies. The author's involvement in training early career researchers, both in formal training sessions and one-to-one sessions, over a long period, allows for user responses and experiences of the resources to inform this examination.

There is a wide range of sources that might fruitfully be used in criminological research. This article, by Andromachi Tseloni* and Nick Tilley**, overviews the type of evidence used in research that has recently appeared in the British Journal of Criminology, gives examples of unobtrusive administrative data that have been used in recent projects, and focuses on a single data set, the Crime Survey for England and Wales, which covers a wide range of criminological topics. Finally, it will be suggested that criminologists may be missing opportunities to draw on valuable data sets that, though imperfect, could be useful to them in their research.
