Harp Week - Explore History"As a retirement project, [John Adler] decided to have this uniquely important journal [Harper's Weekly] manually indexed. Harper’s Weekly never had a useful index, so until now there has been no way for students and researchers to access the illustrations, cartoons, news, literature, editorials, and ads that these volumes contain without spending hours poring over microfilm or locked-up original copies in rare book rooms of libraries. Harper’s Weekly is really the only consistent, comprehensive, week-to-week chronological record of what happened world-wide in the last half of the nineteenth century."
