Since author names appear differently in different languages, it would probably be good to consolidate different versions under one - so it would appear during search regardless of its spelling (e.g. whether it's Jo Walton (English), Джо Уолтон (Russian) or whatever it looks like in, for example, Chinese).

Right now if I search for Джо Уолтон, I won't get any hits, but if I search for her book "Среди других" (Among Others) - I will. So, aside from gathering various spelling/languages under one heading, it might be also prudent to display the author's name in the language the book is under.
