I too am returning to classical guitar after many years away, but I am trying to avoid any scores with tablature because I know that being able to read standard notation while being more difficult at first, will open more choices later.
I am using a book that appears to be out of print. “Classic Guitar Solos book 1” by Jerry Snyder. It covers a wide range of graded easy to intermediate music, and unlike most of his current books is in standard notation only. It was published in 1978, and having already owned it and used it in the past, I dug it out again, and I am starting from the beginning.
I did a search and found one copy listed on e - b a y, nowhere else.
