Alphabetical Pagination

Hi all,

I’ve created a custom post type which will contain a couple of hundred different options. As well as sorting by the taxonomy I am trying to create an A-Z list which takes the first letter of the each post. like so

A B C D E F G… (etc)

B:
Ben
Bill
Boris

I don’t think there are any wordpress functions for this so I presume I will need to make a loop going through the alphabet, but i’m not sure how i will get it to actually show those one’s beginning with the selected letter.

Any advice is much appreciated

Thanks
