Mono Monday- By the "Wayside"

Which of these books are going to "fall by the wayside", ie I will stop using them and take them to the charity shop. Major clearing out of all the bookshelves and putting them in piles by author.  Mr P wanted to read a specific author "in order" which prompted me to have a clear out. Two bag fulls have gone "by the wayside" already and the Oxfam Bookshop said thanks very much. 

Statistics-  I have three piles of S, 2 of M & J and no Q, X or Y.
