Word I ignored in title sort

I noticed that when sorting alphabetically by title, LT ignores the word I when it is the first word of title. Of course, one ignores a, an, and the.
Example: Buber's "I and Thou" is found between AM and AP in book listing sorted by title.
Why does LT ignore initial word I?

There is a field next to the title under "edit your book" that picks the number of the character that the sort should use. I suspect that your title is set to 3 (not 1, which would be I, and not 2 which would be the space). If you change that it should sort correctly.

Thanks. Now I know how to sort properly.
