Retired Rep. Carolyn McCarthy has donated her papers from her nine terms in office to Adelphi University in Garden City – though she said she never officially attended the school. But McCarthy said she did sit through a biology class in 1963 without registering, and Adelphi did give her an honorary doctor of laws degree in 1997. The Mineola gun control activist turned Democratic politician said she began shipping boxes to Adelphi before she retired last year and was still sending them last week. Archivists are cataloging her papers and hope to make them available by the fall. You can get a peek of some photos and files now: An exhibit called “Carolyn McCarthy: A Representative Life” opened last month at Adelphi’s Swirbul Library. It runs through Sept. 10.
