Phil Tresadern (Letters, 20 August) does not appear to favour Wikipedia, even if quoted by Bruce Charlton (Letters, 13 August).
As every school and university student knows, Wikipedia is not a research journal (although it is peer reviewed). It is an online encyclopaedia with online and offline sources, and those sources can be anything that might verify the content of a Wikipedia article.
In the past few years, the drive to cite references and sources has grown, and Wikipedia stands (at 3 million articles in English alone) to be a fascinating and reliable resource, as opposed to much of the material to be found on the internet.
