There are a variety of printed sources for situation puzzles. Unfortunately, most of these books are out of print and extremely difficult to find. (Also unfortunately, many books that do contain situation puzzles mix them indiscriminately with well-known riddles and logic puzzles.) Try inter-library loan, and be prepared to wait. If you know of printed sources other than those listed, please send me bibliographical info.

I've included a few puzzles from these books which weren't in previous editions of my list; in those cases I've paraphrased the puzzle statements and cited the sources. Perhaps eventually I'll contact the copyright owners and ask for permission to include more items from the books...

Ballard, Jim, Stories With Holes (Mandala Press(?), location and date unknown (but apparently between 1975 and 1981)). A slim volume containing twenty situation puzzles, plus instructions for playing them with an elementary school class. None of the puzzles are original to Ballard; in fact, most of them come from How Come? and How Come -- Again?, by way of the folk process. Ballard calls the puzzles "computer games" because the puzzle-presenter is supposed to act like a computer and answer only "yes," "no," or "does not compute." Contains no publishing or contact information whatsoever, even though it asks for submissions for future volumes. Very hard to find. May or may not be connected to a series of at least 18 other volumes written by Nathan Levy between 1990 and 1992, all of which contain the phrase "stories with holes" in the title.

Downie, Diane, Twila Slesnick, and Jean Kerr Stenmark, Math for Girls and Other Problem Solvers (Lawrence Hall of Science, University of California, Berkeley, 1981). Contains one or two new puzzles, several interesting variants, and a lot of unrelated but interesting material on teaching problem-solving. (Note that this is not the same as the book by Carole Marsh with the same title.)

Games magazine (bibliographical data unavailable). They ran a situation-puzzle contest some years back (in 1992?), but I never saw the results.

Morris, Scot, The Next Book of OMNI Games (bibliographical data unavailable; out of print). Most of the puzzles I've been told from this book were printed earlier in one or the other of the Agnes Rogers books.

Rogers, Agnes, How Come? (1953: Doubleday & Company, Inc., New York). Library of Congress catalog number 53-5756. OCLC #1612919. The author may also be listed as Agnes Rogers Allen. With its sequel (see below), the classic volume on the subject; is probably the original source for quite a few standard situation puzzles, though Rogers says she does not know who invented the form. Nor does she know the source of most of those she includes -- like all good folklore, situation puzzles are difficult to trace to their origins. (Rogers says about half the items in this volume, and all the items in the second volume, are original to her and her friends.) Unfortunately, both these books are long out of print. Besides their historical value, these two come furnished with delightful illustrations of various wrong approaches to some of the puzzles. These versions were definitely intended to be read from the book, though; the puzzle statements are much lengthier than the versions in my list.

Rogers, Agnes, and Sheehan, Richard G., How Come -- Again? (1960: Doubleday & Company, Inc., New York). Library of Congress catalog number 60-13745. OCLC #2580602. Again, note that all the puzzles in this volume are original to Rogers and Sheehan.

Sloane, Paul, Lateral Thinking Puzzlers (1992: Sterling Publishing Co., Inc., 387 Park Avenue South, New York, 10016). ISBN 0-8069-8227-6. There's a lot of overlap here with the rec.puzzles archives, including a lot of puzzles that I wouldn't even consider doing as situation puzzles (such as the infamous "12 balls" problem). Still, it does have one or two nice situation puzzles in it. Warning: these are not lateral thinking puzzles in the sense in which I use that term -- each puzzle has a definite correct answer, and creativity and sideways leaps of logic aren't rewarded unless they result in that answer. Cover price $US 4.95; should be available or orderable from most bookstores in the US.

Sloane, Paul, and Des MacHale, Intriguing Lateral Thinking Puzzles (Sterling Publishing Co., Inc.). ISBN 0-8069-4252-5. Also in the series: Challenging Lateral Thinking Puzzles, Great Lateral Thinking Puzzles, Test Your Lateral Thinking IQ, and Improve Your Lateral Thinking.

Weintraub, Richard, and Krieger, Richard, Beyond the Easy Answer: exploring new perspectives through creative problem-solving games (1979: Zenger Publications, Inc., Gateway Station 802, Culver City, CA 90230). ISBN 0-934508-00-3. Contains a variety of puzzles and games, most of which aren't really situation puzzles (and many of which are in the rec.puzzles archives), plus some creativity games. Out of print.
