PSA: The local library's book sale in Portland showed me something about modern covers
Three years ago, I bought a stack of old hardbacks there for rebinding practice. Last month, I went back and saw a clear change. The newer donated books had covers that felt thin and flimsy, almost like thick paper. I tried to fix a split spine on one last week, and the cover material just tore. Has anyone else had trouble working with these newer, cheaper cover stocks?
