I would say almost all of the Soviet era Mir Publishers books are like this. Small, succinct and information-dense.

As an example, Vygodsky's 2-vol "Mathematical Handbook" (Elementary Mathematics & Higher Mathematics) and Yavorsky & Detlaf's "Handbook of Physics" have ungodly amounts of knowledge in a relatively small size books.
