These links are to other, 'external' web sites.
They will usually open in a new window or a new tab.
The content of these sites is not my responsibility.
Their inclusion in my links section does not include any warranty that they are helpful, useful, interesting or relevant to you, but many of them probably are!
I have arranged them into what I hope will be a helpful categories.
If you find any bad links, or have any suggestions for sites to link to, please contact me.
