Don't you just mean you want some kind of index and jump within the page to the corresponding list, something like this:
<html>
<body>
<p>Index</p>
<a href='#a'>Go to A</a>
<a href='#b'>Go to B</a>
<a href='#c'>Go to C</a>
<p id = 'a'>Links starting with A</p>
<a href="">adam</a>
<a href="">apple</a>
<a href="">average</a>
...
<p id = 'b'>Links starting with B</p>
...
<p id = 'c'>Links starting with C</p>
...
<p id = '...'>etc...</p>
</body>
</html>
Good luck!
