It was probably the first book on data structures and algorithms I came to possess (likely from a library book sale as a teen), so I would say I learned a lot from it, but don't remember the particulars. I remember it being clear and to the point, even though I didn't use Pascal, with good diagrams and nice printing. I read it as pseudocode.
It was a very compact hardcover edition that I could carry around easily in my backpack.
And it had a memorable title.
