     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between probe identifiers (key)
     and PubMed ids (value), which are subsets of publications
     associated with the underlying genes corresponding to the probe
     ids. Keys can be accessed using ls(name of the environment) and
     values using get(key, name of the environment) or mget(keys, name
     of the environment). Values may be vectors of length 1 or greater
     depending on whether a given probe identifier can be mapped to
     only one or more publications. Mappings between probe ids and
     PubMed ids were obtained through their mappings to LocusLink ids.
     NA is assigned to probe identifiers that can not be mapped to any
     publication at this time.
