				<para>
    We present the results of an isophotal shape analysis of three samples
    of galaxies in the Coma cluster. Quantitative morphology, together
    with structural and photometric parameters, is given for each galaxy.
    Special emphasis has been placed on the detailed classification of
    early-type galaxies. The three samples are: i) a sample of 97
    early-type galaxies brighter than m_B_=17.00 falling within one degree
    from the center of the Coma cluster; these galaxies were observed with
    CCD cameras, mostly in good to excellent resolution conditions; ii) a
    magnitude complete sample of 107 galaxies of all morphological types
    down to m_B_=17.00 falling in a circular region of 50arcmin diameter,
    slightly offcentered to the North-West of the cluster center; the
    images for this and the next sample come from digitized photographic
    plates; iii) a complete comparison sample of 26 galaxies of all
    morphological types down to m_R_=16.05 (or m_B_=~17.5), also in a
    region of 50arcmin diameter, but centered 2.6degrees West of the
    cluster center. The reliability of our morphological classifications
    and structural parameters of galaxies, down to the adopted magnitude
    limits, is assessed by comparing the results on those galaxies for
    which we had images taken with different instrumentation and/or seeing
    conditions, and by comparing our results with similar data from other
    observers.</para></description>
