Links at top of page
(A HREF="#A") A (/a)
(A HREF="#B") B (/a)
and so on through the alphabet.
Place this at the beginning of the A section
(a name="A")A(/a)(br)
Place this at the beginning of the B section
(a name="B")B(/a)(br)
and so on through the alphabet.
You should also place this at the top of the page:
(a name="Top")(/a)
and this at the bottom of each alphabetic section:
(A HREF="#Top") Back to Top (/a)
so that your visitors will have a way to get back to the top of the page and the alphabet links with only one mouse click instead of having to scroll or page up.
