Now, I'm aware that their list is not a complete match. I would guess that they include Horror, which a lot of Hugo voters wouldn't. But what I only realized as I came close to finishing the merge, is that their list has not apparently been vetted at all, as I found two short story collections and a non-fiction reviews book listed.
The real mystery now is: How many of the other titles that i so blithely added to my list are inappropriate?
And how do I tell? And what do I do about it? (Well, obviously, remove them as they are found.)
So now the next step (I still need to add a bunch from Scalzi's list) is to include a comment about if the title has been verified (like, the author or publisher says it is). And maybe this would be a good time to add what format the book is in as well - something I wanted to add anyway. But then there's the very real issue of not spending more time on this than is warranted. And since it's just a hobby-task, that's probably no where near as much time as it would really need.
Bottom line, we shall see. But I am for sure going to add a field for Source from now on!
