I bought this reference probably 5 years or so ago, and scanned through it at the time I purchased it. I took a second look at it last night.
Any list of this sort is going to have deficiencies, and this one definitely does. It is extremely heavy on "contemporary" fiction, particularly fiction published in the 1990's and 2000's, and some of the choices are really strange.
For example, there is only one Willa Cather selected - My Professor's House - and the compiler completely ignored My Antonia, Death Comes For the Archbishop, and her Pulitzer Prize winning WWI novel, One of Ours. There's one Agatha Christie - The Murder of Roger Ackroyd, which is a great one, but not And Then There Were None.
And my edition has 7 entries by Paul Auster. I don't know who he bribed, but that's ridiculous. There is no way that he has written 7 books that are worthy of inclusion in a list that purports to be 1001 of the greatest books ever written.
I think that perhaps we need a BL crowd-sourced list. What do y'all think?
