NASA's International Halley Watch (IHW) has created a Comet Halley Archive. The collection of data spans the full wavelength range as submitted by scientists to the IHW. The observations belong to one of the following Disciplines: Amateur, Astrometry, Infrared Studies, Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, and Spectroscopy and Spectrophotometry. The data collected by these nine disciplines were augmented by Spacecraft measurements. The data were submitted to IHW, but the evaluation and selection for the Archive has been the primary responsibility of the Discipline Specialist Teams for each network in cooperation with the Lead Center. The Infrared Imaging subnetwork contains 66 images of Halley and 29 images of calibration stars (HD18881, HD3029, HD10560, HD10696, HD12965, BS134, BS923, BS1856, Beta Pegn Rho Ori) for dates spanning 1985 March 11 through 1986 May 23.

The data from the Large-Scale Phenomena Network has been compressed images of Halley and 173 data used for calibration. The calibration data consists of the following: laboratory data (CALIBRATION_SPOTS, PHOTOMETRY WEDGE), standard stars (STDSTARS, STAND_ STAR, AQR STAND, COMA STAND), and open clusters (NGC1039, NGC1817). These compressed images, spanning dates 1985 September 21 through 1987 April 25 comprise the first 18 volumes (Image Data) of the IHW Chronological Data Archive Collection. A set of subsampled or 'browse' images covering the same date range is on volumes 19 trough 23 (Mixed Data) of the IHW Chronological Data Archive Collection. In addition to the digital archive, 'The International Halley Watch Atlas of large-Scale Phenomena' (Brandt, John C., Niedner, Malcolm B. Jr., Rahe, Jurgen, 1992) provides many analogue images of the data in both black and white and color representation.

The data from the Amateur Observation Network contains 2170 entries of photographic materials. The data files (which are kept at JPL) consist of five types as follows: contact prints, negatives, prints, slides, and transparencies through 1988 February 16.

The data from the Large-Scale Phenomena Network has been organized into a set of digitized images and those left in the original analog state for reasons of quality, time coverage, or submission problems. These latter 1771 pieces of data are held in an archive both at Goddard Space Flight Center and with the Small Bodies Node of the Planetary Data System. (In the latter case, contact specifically the Comet Sub-Node of the PDS at the Laboratory for Atmospheric and Space Physics associated with the University of Colorado Boulder, for more assistance). Some of these analog images are presented in 'The International Halley Watch Atlas of Large-Scale Phenomena' (Brandt, John C., Niedner, Malcolm B. Jr., Rahe, Jurgen, 1992). The data cover a time range from 1984 December 22 through 1987 April 26 through 23 of the IHW Chronological Data Archive Collection
