What's the idea behind this then, since a website doesn't normally recommend books? It's because electronics is a vast field that covers a multitude of sins and I don't care if you are the Professor of Being Very Good at Electronics at Electronic University in Electronic City in the Country of Cleveratelectronicsia - even if you are you still can't possibly know everything. For instance, I'm good at control systems (I don't know everything though). I know a bit about DC motors. I know less about AC motors and have to look stuff up. Usually I can knock together or mend an electromechanical device, and radios are a field I'm particularly strong in.
Now ask me what's going on under the bonnet of this computer I'm currently typing on. Here's what I'll reply:

"La la la la la-------- I'll get back to you on Wednesday with that."

Unless of course you ask me on Monday or Tuesday when the reply will be that I'll get back to you next Monday with that.

The reason behind that is I haven't got a clue, and what I'm going to do is fervently pray that I can get hold of a book that tells me what's going on. Then I'm going to hit it hard and hope that what you've asked me becomes apparent. If you're at school at college, this is what your teachers are or have been doing all the time. The older ones need less recourse to the books, because they've done it years before and the same question has cropped up every year since. But still at least once a school year they get a stumper which sends them scurrying off to the bookshelf. So here, as far as electronics is concerned, is what they are looking at:

You'll notice I mention Waterstone's a lot in this bit. That's not because I have any shares in it (I haven't) but because they run a loyalty card scheme. Every time you spend a tenner, they give you a stamp on your card. When you get ten stamps you get a £10 book voucher. It's delightfully low-tech- the card is cardboard and they stamp it with an old-fashioned library stamp. Consequently I always go into Waterstone's if I can to buy books, otherwise it's WH Smiths, last resort It's Amazon.
Plus the Waterstone's in York is HUGE. You could spend hours in there. It's on High Ousegate (28-29) and it's got very comfy sofas and smiley staff.
I like the one in Meadowhall next to M&S too- not nearly as big but the staff are really nice and point you in the right direction.

Buying from Amazon is often cheaper and the range is unbelievable- I'm convinced there isn't a book in or out of print that Amazon can't source. To test it I looked for "Air Patrol and the Underwater Spies" by Paul Buddee which is a book I had in the 1970's. It found three copies for sale.

Success in Electronics by Tom Duncan

A practical book which is useful for those doing BTEC II and III or City and Guilds 2240 (Servicing) and some use for those doing A level courses in Physics, Electronics or Design . Although complete beginners may glean something from it, it's not really suited to them and a simpler book to start with will lead to a better understanding of the level of this book. First published 1983, revised 1987- 1997(2nd Edition) and 2008 and available from Amazon.
