Whilst "collections" of bookmarks for chemistry materials on the Web continue to vary in quality, and many fail to really review, structure or categorise the materials, there are signs that more resources are being devoted to this important area. Thus http://www.wiley.com/college/webercises/ provides a good structural overview of some of the chemistry out there. There are hints from this site, coming from a major publisher as it does, that we might expect the quality assessment aspect to improve in the future. Dr Henry Rzepa, Dept.
