Paul Gilster’s Digital Literacy (John Wiley, £15.99, $22.95,
ISBN 0 471 16520 4) contains a useful 150-page booklet about how best to use the
Internet as an information source and how to judge the quality of its contents.
This booklet boils down to chapters four, six and seven—the other chapters
ramble on about the Net’s future and offer basic explanations of the nuts and
bolts which are better presented elsewhere. Don’t be put off: the clear,
well-written explanation of research techniques are worth the price. And you can
always ignore the rest.
