does anyone know of the differences, if there are any, between the 1991 batsford edition of this book and the more recent dover edition?

i was thinking about buying it and saw a cheap copy of the batsford edition, but was wondering if it was worth getting the more recent one instead?

The Dover 2001 edition had a few minor corrections, or so it says on the page with the publication info.

thanks!

got this in the post today. on first impressions i think i will get a lot of use out of it. just enough helpful annotations and LOTS of examples to play through.
