Cohomology operations are at the center of a major area of activity in algebraic topology. This treatment explores the single most important variety of operations, the Steenrod squares. It constructs these operations, proves their major properties, and provides numerous applications, including several different techniques of homotopy theory useful for computation. 1968 edition.
This review is from: Cohomology Operations and Applications in Homotopy Theory (Dover Books on Mathematics) (Paperback)
This is a great fast paced introduction to several structures in homotopy theory, by way of carefully explaining Steenrod Squares. You need to understand basic algebraic topology homology/cohomology/homotopy groups very well already, up to the point of obstruction theory and ideally Postnikov towers to take good advantage of what the book offers. The first chapter is an introduction to Eilenberg-MacLane spaces with a 1.5 page review of obstruction theory. The book is well written and pedagogical for the advanced student.
