    Contact prints and contact print negatives

    Manuscripts

    This subseries contains contact prints of the photograph albums and were used as circulating copies in the reading room prior to the digitization of the original albums in 2016. Note: Many of the contact print images are of poor quality. The albums were photographed in in 1976, prior to the donation of the originals in 1983, when the Shepard family loaned the albums to the Library for the purpose of copying. Each photograph was copied (and each page of the album was also copied in its entirety) on thirty-five millimeter roll film. Contact prints of these photographs were assembled and made available for reference. Image reproductions made from the contact prints were ordered using the numbers printed on the negatives (in addition to the JPL album number and volume number). The contact print negatives were removed from Boxes 513-516 and are now housed 20 3-ring binders, binders 1-20.
