Filter Results Sorted by Title Alphabetically

I was able to find a solution. By replacing my themes’s archive.php (Other themes might use category.php) loop function with the code below. Replace ‘Category’ with the name of the category you would like sorted alphabetically by title.

<?php
// we add this, to show all posts in our
// Glossary sorted alphabetically
if (is_category('Category'))
{
     $posts = query_posts($query_string .
'&orderby=title&order=asc&posts_per_page=-1');
}
// here comes The Loop!
if (have_posts()) : while (have_posts()) : the_post(); ?>
