It's excellent news that the LMS are to re-publish <a href="http://www.lms.ac.uk/CasselsFrohlich.pdf>Cassels & Fröhlich. There are many other excellent mathematics books which are just about impossible (or at least very expensive) to get hold of, though this problem seems to be getting a bit better with some texts being printed on demand.

Which book(s) would you most like to see re-published?

A couple of comments:

Perhaps nobody under 30 actually reads real books made from trees any more, but personally I find it more convenient to refer to a paper copy, to the extent that I will happily buy a copy of something which is available free on-line (like SGA 1 and 2, or Milne's Arithmetic Duality Theorems).

And of course there can be legal issues with re-publishing works - EGA & SGA seem to be a case in point at the moment.

Here are two to start off with:

• Manin, Cubic forms
• Grothendieck et al., Dix exposés sur la cohomologie des schémas

(not including Cassels & Fröhlich because I picked up a copy on Amazon a couple of years ago :-) )
