thepianoplayer416 I think of buying sheet music as a 1-time fee. Sheet music is not all very expensive.
I don't know about your budget, but to me, $55 for one piece is a bit steep.
I use library books all the time, either for the same scenario as @twocats when I need just one piece, or when I'm trying to decide whether I want to buy something or not.
I am a bit spoiled though, because I've always had a university affiliation, so I've enjoyed great access to all kinds of scores as a result.
