"A" and "The" are not alphabetical
When listing items, titles that begin with 'a' or 'the' (the indefinite and definite articles) should not be alphabetized under 'A' and 'T', respectively. They should be alphabetized based on the beginning letter of the first non-article in the title. This is standard practice and it is ridiculous to do otherwise.

This is standard practice, and it just makes sense from a patron/searcher point of view

I would also include "An" which should be ignored
