Reviews have been around as long as people have responded critically to texts produced by others. The rhetoricians of Ancient Greece can be thought of as establishing standards, principles and procedures in terms of which the spoken texts of orators might be reviewed and criticised.
In Ancient Greece, of course, reviewers would have had to restrict themselves to considerations of the texts available, for example, plays, public speeches, epic and lyric poetry, and histories. Nowadays, the range of texts lending themselves to the activity of review writing has expanded enormously as has the range of publications in which the review is a major genre. On the New Zealand scene, for example, Landfall specialises in reviewing literary texts, Rip It Up focuses on the reviewing of popular music, the Listener specialises in reviews of plays, books, films and videos, television and radio. In fact, it's hard to find a publication that doesn't include a review section.
A review has two main functions. The first can be thought of as a narrative which puts the reader in the picture by backgrounding the text's production or saying something about its producer, and summarises the text's content. The second function is evaluative. Here the review writer argues for their opinion of the text on the basis of certain criteria.
Review writing is a risky business, as anyone who has gone public with a review knows. You don't have to look far among letters to the editors to find reviewers being attacked for their views. Occasionally, reviewers are attacked because they have not got their facts right. Usually, however, the disagreement occurs over the reviewer's choice of evaluative criteria.
How might the medium of hypertext help a reviewer in the review functions? Primarily, review writing can be thought of as an intertextual act. It is usually incumbent upon a reviewer to place a text in relationship to other texts, both those produced by the maker of the text under review, and those that the text under review alludes to in some way. Hypertext allows these links to be inserted as "hot" into a review text. It also allows hotlinks to be made to sites that are relevant to the reviewer's own frame as they undertake the review task.
The sites the links below will take you to provide examples of the review genre that can be found on the World Wide Web. Where the review makes deliberate use of hypertext to advance the review function(s), it will marked [HPT].
