Recently digitized children’s books available in Readex collections include three that show the interplay between adult work and child’s play—opening up newly accessible vistas in areas such as visual culture and child studies. In my tenure of over thirty years at the American Antiquarian Society, I have either cataloged or supervised the cataloging of the books in the AAS Children’s Literature Collection.  This position has given me great control over the production of high-quality, detailed catalog records that provide rich metadata for author (many of them were women who did not sign their actual names to the books that they wrote), publisher (including many from towns outside of the major publishing centers of New York, Boston, and Philadelphia), illustrators (documenting the people who worked as artists in Antebellum America), provenance (providing access to elements like owner’s inscriptions and hand-colored illustrations), and subjects.  Subject analysis is particularly important in the effective cataloging of eighteenth- and nineteenth-century children’s books because many are chock full of contemporary societal attitudes toward issues like child labor, play, sex role, war, and slavery, but they generally have euphemistic titles that reveal very little about their contents.  These catalog access points provide the intellectual infrastructure for present and future generations of researchers to examine relevant children’s books in ways that would have been impossible before they were cataloged, and thanks to Readex, scanned copies of these books and their superb metadata are now widely available to researchers worldwide.
