Another great, untapped resource for reading librettos of musicals are public libraries, or even more, college/university libraries if you are affiliated to one. I read countless of librettos for so many musicals when I was in college.
SHE LOVES ME has such a lovely libretto. It plays like gangbusters in the current revival.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
