There is this being circulated on the internet recently:

But it's not quite accurate or up to date, particularly with regard to service stock. The passenger fleet bits seem to be more or less OK though.
Capital Transport Publishing used to do a good Underground fleet book, but I don't know if they still do it or when the last one was.
If that is the one by Brian Hardy then the last one that I am aware of is the 2002 edition - there were rumours that a new version was being produced last year but I have not heard anymore since then.
There is a Tubegroup on Yahoo Groups and if you join that and look at files you will find one that shows a LUL stock listing in Excel format.
It's later this year that the new book is expected to be out.
The list on Tubegroup is the one I have posted above. ( 12CSVT - yes, the S Stock would have been as at the date that list was compiled, but as I pointed out there are a number of inaccuracies and outdated details... )
