Dear All, Thank you very much for your replies. Just one more time I got to feel what a treasure of information the list is. Curtis and Gene, thank you for recommending the books. Now I have yet more books to look for. :))) And Tony and Ann - thank you for reminding me of Christina! How silly of me - I should have remembered to ask her myself! I even have her wonderful book. Good luck to all! Fyodor. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
