Types of information source included

The information which appears on the site has been gathered from a number of sources. They have been grouped in three complementary lists:

• The Bibliography is a list of published sources of information which are quoted, or referred to, on the site. The sources are mainly print-on-paper-based, but information stored in other physical forms, eg, audiotapes, will be included whenever appropriate. The bibliography, which also includes a few non-published sources, is arranged in broad subject categories.
• The list of directories can include sources stored in any physical format of directory, eg, print, microform, cd-rom.
