Glad to see I'm not the only one who thinks this - it's one of the many areas I need to look at, and saw that recommended elsewhere... took a look on Amazon and got completely intimidated! If 1000+ pages is an introduction, what does the chapter and verse look like?

(I've started reading Grokking Algorithms this week, and it's been a much better introduction - I know it's not as in depth as some other books, but I'm making good progress with it and not drowning in complexity from the get go)
