... However, these advances also present problems for the management of data sets, including problems with data quality and the proliferation of multiple versions of data sets. It is possible that irreplaceable data bases could be lost because of the lack of a general consensus within the geomagnetic community about how they should be managed.

... Furthermore, the sole copies of many data sets that are the results of completed projects data never sent to any data center—may be stored, with or without cataloging, on shelves or tape cabinets at research institutions. Scientific personnel are needed to identify and retrieve such data for inclusion in the general geomagnetic data base.

... On-line data access is currently available for some applications and is very appealing to users who can simply download data directly into their computers. But large data bases that are continually being updated require large storage spaces and can sometimes be {abor-intensive.

... · As part of the national geomagnetic initiative, special attention should be given to stewardship of data. The activities of centralized and distributed data centers should be integrated to achieve the fullest utilization and to maintain the highest quality of existing and future geomagnetic data sets.

... There should be close coordination among the principal partners concerned with developing, cross-checking, and using the International Geomagnetic Reference Field, particularly universities, NASA, the U.S. Naval Oceanographic Office, the USGS, the British Geological Survey, {ZMIRAN (the Russian Institute of Terrestrial Magnetism)
