John Glasby’s 1971 ‘Variable Star Observers Handbook’ was a treasure to me in the years between my first VS observations (1975) and joining the BAA and the BAAVSS (1978). Lots of controversy about Glasby of course, but I found this book invaluable.
Sidgewick’s 1971 edition ‘Observational Astronomy for Amateurs’ rarely left my side in my early observing days too, along with his ‘Amateur Astronomers Handbook’ of the same year. I still treasure those books.
My 1965 Ladybird book of Astronomy remains in pristine condition, and I guess this must have been the first book I used with my first telescope in 1965, closely followed by Nortons 1950 epoch star atlas.
Gone very nostalgic now…
