Updating the shortshort list

I'm finding that my short (short) list of books to read has grown larger and more unwieldy than I'd like (about 90 books), and should probably be revised. So I thought I'd post it here for the following:

• Comments on any couple of books that you think are most worthwhile to be on the shortlist.
• Comments on any couple of books that you think are least worthwhile to be on the shortlist.

Obviously I'm looking for your opinion, and not whichever book has had the most impact on 19th century social trends, or whatever lists happen to measure...
And there's probably no point in suggesting other books to be promoted to the list since you won't know what I've read, but still...
Feel free to add qualifiers.
