I ran onto this one while looking for something else.  Although it's not new, I thought it was interest, especially how different some of the names were.  It's the Grobius Shortling Mystery List:

I'd try to copy/paste it but my experiences haven't been good with that.  There are some authors who seem a bit over-represented, some that I'm surprised to see at all, and others that I'm glad to see.  I'm not saying he shouldn't be there, but I've never warmed to Robert Barnard.

(There's a selection of Reginald Hill there, BTW.  Thanks for making those recommendations, JK H)

Oh my.  I've only read two on the list and I didn't like either one of them.....

I've read 13 of the listed books.

I put my count at around 22, although there are some I can't remember specifically.  It may be more but I read some of those authors so long ago that I would have to start the book and then realize I've read it before.  I can always count on having read all of Dame Agatha at one time (gee, she was alive then <gulp>). 

Since I like some of the old ones, I enjoy looking through the lists for something "new" to read although it can be a challenge to find a copy. 

I don't recall Jonathan Gash on any lists, although I enjoyed some of his mysteries and still recall a bit of trivia from on :).  Did anyone else find a choice surprising?

I've read 11 of them but like Diana, my numbers may be higher.  John MacDonald and Ian Fleming were in a different lifetime, it seems like.   I have a couple of Innes books on my shelf that I've tried and tried to read.  I KNOW they are good but they just don't grab me at this point in my life.  I finally posted them.  Maybe I'll actually read them before they're requested...who knows?  LOL

Thanks for sharing.  I love those lists!
