Storage
Introduction
  • Storage Environment for photographic plates will
    have fairly constant temperature and humidity.
  • Storage Space at PARI is already equipped with an
    adequate air-conditioning system and a solid
    foundation for firm, long-term storage.
  • Storage Enclosures. Plate envelopes that are
    damaged or corrosive will be replaced by acid-
    and lignin-free ones. In those cases, original
    envelopes will be kept separated from the plates.
  • Storage Systems. Collections will be maintained
    in the original storage cabinets. Collections
    without adequate cabinets will be stored on steel
    shelving.
  • Plate cleaning. Emulsion sides will not be
    touched, identification marks will be preserved.
  • Plate Copies. Plates deemed to be severely at
    risk such as
  • broken plates
  • plates with emulsion peel
  • plates with fungal growth
  • will be copied photographically as soon as
    feasible.
  • Our shared heritage of some 3 million
    photographic observations is seriously in
    jeopardy, and astronomy may well lose vital,
    unrepeatable data dating back over a century.
  • A call for preservation of astronomical plates
    has been made by the international astronomical
    community.
  • This project is in response, and aims to
    establish a national archive for astronomical
    plates at the Pisgah Astronomical Research
    Institute (PARI) that will
  • Ensure the preservation of North Americas
    astronomical photographic heritage (Phase 1) and
  • digitize selections of those collections (Phase
    2)
  • We describe details of the storage, cleaning and
    cataloging procedures that have been planned for
    Phase 1, and provide an overview of what is
    anticipated for Phase 2.

Basic Steps
  • Prepare the storage areas.
  • Appraise all U.S. collections.
  • Test methods for handling, cleaning, preserving
    and re-storing damaged plates.
  • Develop on-line database and finding aid
    including log-book and card index sorting.
  • Adopt IAU cataloging and meta-data standards
    where they exist.
  • Furnish a laboratory for plate examination and
    measurement.

Phase 2 and Beyond
  • Select appropriate digitizing methods and
    equipment.
  • Digitize selected collections or sub-sets.
  • Continue plate storage and preservation so that
    every USA collection has a guaranteed safe future
    either at home or PARI.
  • Establish the PARI preservation and digitizing
    scheme for astronomy world-wide.

Phase 1
  • Establish list of priorities for US collections
    at risk.
  • Receive at-risk/unwanted collections at PARI.
  • File and enter into database.
  • Scan log-books, observing note-books,
    manuscripts.
  • Provide public access to completed catalogs.
  • Hold a workshop at PARI to review achievements
    and plan for Phase 2.
