While recently reading a 1950s used paperback by John D. McDonald, I fanned the pages in front of my nose and told my wife: "If they could bottle this smell I'd wear it as cologne."
She said I'd smell like an old man. She's wrong (but don't tell her that).
As Keith Roysdon writes at crimereads.com: "Just as smells of your mother’s cooking are an important part of memory and nostalgia, smell is a big part of longing for a proper used bookstore."
It's a fun read, but I think used bookstores are more popular and prevalent than he thinks. We are fortunate to have two good used bookstores in Rapid City, plus an independent bookstore and a BAM. Not bad for a small city.
