There's a recommended book on algorithms which is very nice (red cover, but can't recall title).

Bit of a tangent, but, for anyone who's interested, I'm guessing the book was Steven Skiena's The Algorithm Design Manual [0], as it is well-regarded and has a red cover.

Also, even more tangentially, there are videos of the author's Algorithms course lectures online from 2012 which I went through once and they were pretty good [1].

(There were one or two that had audio issues or issues seeing what he projected on the screen, but there are multiple years' worth of videos, so you can choose an alternate from an earlier year if necessary and the slides are available there too, so you can follow along with them, if need be; audio-only files are are also available if you want them).
