Here's the abstract of a recent suggested paper from the Expository Times.
The Internet offers a vast wealth of academic material, but the sheer quantity of information available can mean that locating relevant, high-quality resources is a formidable task. This article provides an overview of some key websites for theologians,including academic gateways (which offer hand-picked lists of sites for a particular field), library catalogues, and bibliographic databases. Details are also given of some of the growing number of full-text resources that are appearing on the Web (both those available to members of subscribing institutions and those which are freely available to all): collections of classic works,online critical editions, electronic journals, eprint repositories,plus contemporary scholarship and reference works offered by commercial publishers. The article concludes with a brief look at manuscript digitisation projects, interactive sites, the possibilities for communicating with other scholars via discussion lists and blogs, and resources for those involved in teaching.
