Mather Library - Thomas’s purchase of the Mather Library from Hannah Mather Crocker in 1814 after the annual meeting of the Society added some nine hundred volumes to the three thousand then in the collection. Over the following winter, Thomas augmented the brief entries in the donation book by going through the purchase in detail and listing each item with his appraisal of its value. He created three categories for listing the books, one for the smallest books, another for the folios, quartos, and manuscripts, and a third list of the contents of twenty-five bound volumes containing English tracts printed between 1690 and 1730. The first page of one of the three lists in Thomas’s handwriting, “Remains of Mather’s Library Folio & 4to. Purchased by I. Thomas and by him presented to the American Antiquarian Society,” is shown with a shelf of Mather Library volumes, now securely stored in the Stack D vault constructed in 2000.
