Description:
    The  fourth volume of the revised version 1.1 of the General Catalogue
    of Variable Stars (GCVS)  contains  cross-identification  tables.  The
    tables contain all GCVS (including extragalactic variables from vol.V)
    and NSV stars  as well as stars  from the name-lists nos.  67 - 72; it
    also makes  it possible to  find out identifications  between the GCVS
    and the NSV catalogue.

Introduction:
    The  cross-identification tables contain all GCVS vols I-III,V and NSV
    stars as  well as stars from  the name-lists Nos. 67  - 72. The tables
    also contain  stars suspected in variability  since the publication of
    the  NSV catalogue or not present in this catalogue for other reasons.
    We give only source catalogue numbers for these stars.

    We tried to provide as  complete  lists  as  possible  for  the  stars
    identified  with the catalogues HD, BD, CoD,  CPD, BS, ADS and for the
    stars  with preliminary HV (Harvard Variable) designations. As for the
    other catalogues, our task  here was  more difficult  since we  had to
    rely  upon references to source catalogue  names made by variable star
    researchers;  the tables in the present volume reproduce the materials
    used in our work, and incompleteness seems to be inavoidable.

    The  differences between the computer-readable version 1.0 [1] and 1.1
    of vol. IV are the following :
    1. Stars of the 71th and 72th name-lists of variable stars [2,3] have
       been added.
    2. For extragalactic variable stars, we present identifications
       between source catalogues and the GCVS Vol. V [4].
    3. After the  publication of  the NSV catalogue [5],  rather many NSV
       stars  received their final GCVS names (in the system of GCVS Vols.
       I-III [6] and subsequent name-lists). A number of stars have two or
       more  different GCVS names. Recently many GCVS stars in the regions
       of  external galaxies got new  names in the system  of GCVS Vol. V.
       The  first  cross-identification  table  presents  all  aliases  of
       presently-accepted official GCVS names.
    4. Similarly, the second cross-identification table presents aliases
       of NSV designations.
    5. The cross-identification tables now additionally include the lists
       of Harvard (HV) and Vatican (VV) variable stars.
    6. All necessary corrections found during 3 years elapsed since the
       publication of the version 1.0 have been added.
    7. We have excluded our very incomplete lists of cross-identifications
       for X-ray sources (GX, X, XX [1]).

    Vol. IV  version 1.1  consists of 34  cross-identification tables with
    the catalogues and lists arranged, with the exception of the first two
    tables, in the alphabet order  of  the  abbreviated  names  of  source
    catalogues and lists (see Table 1). The first two cross-identification
    tables are, in a certain sense, the main ones: a star present in these
    tables  will enter the rest of the tables only under the name given in
    the first column of the first two tables.
