Another old one I like is Applications of Analog Integrated Circuits by Soclof. The first chapter is dedicated to op-amps, and shows just about every mathematical function you can make with an op-amp.
It also covers
Voltage Regulators
Power Amps
Video Amps
Modulators, Demodulators, and Phase Detectors
VCOs
PLLs
Multipliers, Dividers, Logs
Transducers
A/Ds, D/As, Sample and holds
CCDs
Noise
Optoelectronics
(and they bound the cover on my copy upside down so it really confuses people when they see me reading it!)
