Two of my favorites in the "best small books" area are from Niklaus Wirth: - NW: Algorithms and Datastructures. 179 pages. PDF: http://www-old.oberon.ethz.ch/WirthPubl/AD.pdf http://www-old.oberon.ethz.ch/WirthPubl/AD.pdf - NW: Compiler Construction. 131 pages. PDF: http://www-old.oberon.ethz.ch/WirthPubl/CBEAll.pdf http://www-old.oberon.ethz.ch/WirthPubl/CBEAll.pdf Both books are really brilliant and it always fascinates me how much content he packs into the books. Highly recommended. (I like "Project Oberon" too, but it has probably too many pages for this category [>400].)
