In particular the web pages of national governments and public bodies, international organisations, pressure groups, political parties contain much useful material which is updated frequently. However finding this information can be a very time-consuming and often frustrating process. Use the guide to internet searching to find out more. A dictionary defines a bibliography as a list of books by one author or on one subject. When you are beginning an extensive research-based piece of work you will need to make a detailed survey of the literature already published on your chosen subject.
Bibliographies are a good place to begin.
They supplement the more basic lists of important works which you can find in encyclopaedias, providing either selective or exhaustive lists of books on the complete range of subjects. Items to be included in a bibliography may be selected in a variety of ways. Selection could, for example, be made on the basis of publication date the list comprising all works published before a certain date or later than a certain date. It will be clear from the title or the introduction what are the criteria for inclusion. Exhaustive works try to list everything written about the subject.
