When a book name starts with "A", "An", or "The" the book is included in the section indicated by the initial character of the sort-title. But for a book, such as John Crowley's Ægypt, with sort title Aegypt, things sort of fall apart. The catalog produced gets to this book, using the sort-titles for the order, but notices that the initial letter of the to-be-printed title is not an "A". It forces a new page, places the diphthong/ligature at the top and prints the book and author. It then sees the next book (in my case Aesop's Fables, published with Ae... on Æ...) and sees that the initial character is not the same as the last one. It then forces a new page, prints an "A" at the top and goes on it's merry way.

Fortunately this is the only such book in my library, so I can hand edit the result, but couldn't the machinery that handles initial articles be taught about diphthongs?
