Over the years we all accumulate hundreds of addresses which we think may be useful for future reference.We may even attempt to organise them in a Favourites folder or something similar. What often happens, though, is that this list gets unmanageable or is simply not where we want when we need it - especially when we are using a different PC to where they were saved!

In this section, I have listed some of the links to sites which I have found useful. I shall try to update the lists regularly. Some are of general interest to any visitor but most relate to things that I either teach or have a personal interest in. Perhaps you will find some new ones here that interest you too.

Links have been divided into broad categories in an attempt to make them easier to use but the arrangement has been made after only a short preliminary inspection of some entries. Make your own judgment as to which, if any, might be of use in the future and add it to your own list of favourites.
