I currently have the hardback 1997 version of Collins Butterflies of Britain & Europe by Tolman and Lewington (ISBN 0007189915). It has the purple and white cover with a Peacock wing on the top half.
I am considering upgrading to a paperback version of the new edition. Is it worth doing so?
I also noticed two copies of my older version on Amazon as USED for £44 and £188. Are they really worth that much? If so then anyone want it?!

Regards,
Andrew.
