The Magnetospheric Yellow Pages are a directory that was designed to help you find space physics data. The yellow pages do not provide data. Rather they are a listing of links to other data servers that are distributed around the world (and around the web). Several different lists are provided to make it as easy as possible to find the data that you need. Data servers are listed by data type (e.g. magnetometer data) and by host institution (e.g. University of Colorado). In addition there is a list of project pages (e.g. The ISTP home page) and a list of group & institution pages (e.g. Goddard Space Flight Center's home page) which do not directly provide data.
