Conundrum: Prospero’s Books

Tuesday, August 21st, 2012

Jack Prospero buys individual hard-bound volumes of 31 different Shakespeare plays and an empty six-shelf bookcase to put them in.

He puts 3 plays each on the first and second shelves. He puts 5 plays each on the third and fourth shelves. He puts 7 plays on the fifth shelf, and 8 plays on the sixth shelf.

Within each shelf, the plays are in alphabetical order. The titles are exactly as they appear on this list. Ignoring any leading “The” or “A” articles, they are alphabetized by these exact titles.

And, as it turns out, the plays within each shelf are also in exactly the same order as they appear throughout that very same list!

One of the six shelves has only plays with the letter “F” somewhere in the title. A different shelf has no plays with any punctuation marks in the title. One shelf has more than half of its plays containing the word “King” in the title. Pairs of shelves with the same number of books in each are ordered alphabetically by first title.

Can you list the plays as they appear on each shelf?
