Hi Group, Just discovered that The Merck Manual, Sixteenth Edition is available on-line. I have found the printed version of The Merck Manual to be very informative on all health/disease subjects. I always cursed the tiny print, though! Well, now I can read it on my screen and use any size font I choose. The web address is: http://www.merck.com/!!qw1WA0jwnqw1WB3Wht/pubs/mmanual/ Use your copy and paste function to save the address. You will need to register, it's short, and then you can browse for free. Regards, Margaret Tuchman [log in to unmask]
