Searching for information on the Net is very similar to looking up a book. You turn to the index to look for a particular topic, and on the Net you can use one of the many search engines available…The trouble is that these engines are unintelligent, so that a search usually retrieves thousands of websites– the majority of which are completely irrelevant to your query - and it’s hard to separate the wheat from the chaff… It’s easy to get lost in the flood of garbage which a standard search produces, which is why many patients often despair of ever being able to find anything useful or understandable on the Net.

The problem, of course, is anyone can publish on the net – and it’s not easy to make out whether the information being presented is credible or not! A good website should be accurate, useful, credible, readable, up-to-date and have useful links to other sites - but the most important guideline is to find the source of the information!”
