Beginning in the 1950s, Edwin Wolf 2nd embarked on a biblio'l. quest to reconstruct the library of Benjamin Franklin, which was the largest & best private library in Amer. at the time of his death & was subsequently dispersed. The contents of Franklin's library were virtually unknown until Wolf identified the unique shelfmarks that Franklin used to organize his books. That discovery allowed Wolf to locate 2, 700 titles in 1, 000 vols. that Franklin actually owned. Wolf also identified a further 700 titles owned by Franklin. After wolf's death, Kevin Hayes took up the project & brought it to fruition. This catalogue includes almost 4, 000 books known to have been owned by Franklin, & the Intro. tells the complete story of Franklin's library, its dispersal, & its reconstruction.
