Many thanks for all the useful comments yesterday about the hyperref package.
I now have it working. However it only links the number such that figure 1 has a link for the 1 not the whole 'figure 1'. Is there any way to link the whole thing? Also the backref links from the bibliography only appear as a number of the page. I have read that the old backrefx package used to write (Cited on #). I can't seem to implement this even though it is apparently built into the new hyperref package. Any ideas at all? Geoff
