Did you know this about the title of Walt Whitman’s masterwork? I didn’t:
“On [July 4] in 1855, the first edition of Whitman's Leaves of Grass was printed. It consisted of 12 poems and a preface. The printers were friends of his, and they did not charge Whitman for their work. He helped set some of the type himself. "Grass" is a printer's term; it refers to a casual job that can be set up between busy times.”
Thanks, Writer’s Almanac, for the info!
