Two of my favorites (Score 1)

There's no doubt about it... the most influential book in my career was "Software Tools" by Kernighan and Plauger. With examples in Ratfor (which I actually used in the golden days!), it taught good, reusable design practices by two big names in the Bell Labs/Unix arena. Especially in this day when many programmers can barely cut and paste toolkit code together, this book can still teach a thing or two about software.

My other favorite was more a lesson in good teaching practices which I continually use years afterward: A Fortran Coloring Book by Richard Kaufman is a great example of teaching to the masses.
