Re: Fixing inconsistencies in the list of books

When I added a book to the list a while back I realized that the list is quite
inconsistent in how it lists and even spells authors (and in more minor
nitpicks, punctuation).  The case at hand is "Hans-Juergen Schoenig" and
"Hans-Jürgen Schönig".  The attached patch attempts to make it consistent in
how authors are spelled using HTML entities, and how we list multiple authors.

Longer term it might make sense to move this information to the database and
template the list, but that feels like a low-priority task (if one at all)
given the low churn of this list.
