Book cover The Misplaced Battleship

"It might seem a little careless to lose track of something as big as a battleship ... but interstellar space is on a different scale of magnitude. But a misplaced battleship—in the wrong hands!—can be most dangerous." The world class con man and thief known as the Stainless Steel Rat (diGriz) has another very big problem to solve and this science fiction novella by the great Harry Harrison will see if he can solve it and perhaps four or five more like it before this fascinating and funny tale is finished. 'Use a thief to catch a thief' sounds great but it sometimes has unexpected results.

Book cover The Repairman

This is a collection of 3 of Harry Harrison marvelous early stories that were published in Galaxy, Analog and Fantastic Universe. The Repairman (1958) is a straight fun SF story of a man getting a job done. It is most typical of his later style in series like the Stainless Steel Rat; Toy Shop (1962), a short piece exploring bureaucratic blindness and one ingenious way around it and The Velvet Glove (1956), my favorite for its writing style, fun perspective, sly social commentary on the scene in 1956 and just plain delightful imagination. And he manages to pack excitement and mystery in at the same time.

The World I Live In by Helen Keller The World I Live In

The World I Live In by Helen Keller is a collection of essays that poignantly tells of her impressions of the world, through her sense of touch, smell, her imagination and dreams. My hand is to me what your hearing and sight together are to you. In large measure we travel the same highways, read the same books, speak the same language, yet our experiences are different. All my comings and goings turn on the hand as on a pivot. It is the hand that binds me to the world of men and women. The hand is my feeler with which I reach through isolation and darkness and seize every pleasure, every activity that my fingers encounter...

AMUSEMENTS IN MATHEMATICSby HENRY ERNEST DUDENEYPREFACEIn issuing this volume of my Mathematical Puzzles, of which some have appeared in periodicals and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original...
