I'm sure Theresa (or others) will correct me if I'm wrong here, but doesn't the publisher have a large say in whether or not a book should have a glossary (or map, whatever)?

And since the agent and/or editor has to like the book enough to take it on before the decisions even get as far as whether or not you should have a glossary... perhaps it might be to your detriment if the book depends upon the glossary, since the agent/editor probably isn't going to bother reading a glossary at this early stage.

If that makes sense. Basically, though I love (good) glossaries, I think the narrative should stand on its own merits.
