Books or authors worth to mention - in fact just short list from memory , without mentioning those writen in my native language:
Hersey John - War Lover
Piersig M. Robert - Zen and the Art of Motorcycle Maintenance . An inquiry into Values
hm........this moment I realized that this page must be BIG , even if I choose to mention just authors , without specify titles ; so - I'll put just this two books here , mainly because I open them at least monthly.
So - let me to mention just few technical books :
Manley David - VTL Book
Radiotron Designers Hand Book , preferably 5. edition
