Books that I've obtained from Radio Shack here in the US, by Forrest Mimms seem to be a great place to start for some. The American Radio Relay League (ARRL) has numerous publications including the Radio Amateur's Handbook. The Radio Society of Great Britain (RGSB) is likely to be well equipped. There might be local clubs or flea markets where you could obtain low cost but useful materials and possibly network with others like yourself. Many amateur radio operators do not have EE degrees but do have a strong desire to learn about electronics.
