You might want to consider the following under circuits:
TI Op Amps for All by Mancini. A bias on TI stuff, but that's fine.
Designing Analog Chips by Camenzind. He designed the 555, and it's an interesting read.
Op Amps by AD staff (generally Bryant, Jung and Kester)
The RSGB Handbook. (This is the UK equivalent of the ARRL one, and is a worthwhile complement, even on the same topic, it sometimes has a different perspective)
Experimental Methods in RF Design (ARRL, Hayward, Campbell and Larkin)
High Frequency Measurements and Noise in Electronic Circuits by Douglas Smith. Covers just what it says, and is a bit of an unique book. He also has a great website with a lot more similar info. See
EMC for Product Designers by Williams
The old RCA Silicon Power Circuits (SP-51) is well out of print and dated, but has some handy info in it.
And the MIT "Rad-Lab" series are old, but the basics don't change, and are good for the soul to read.
Some of the above (ie, the first 3) are free downloads at various places and it would be good to annotate them as such.
