Bibliographic Data Base Search Help

Multiple Searches

  • Search terms can be entered in one, two, or all of the search fields.
  • Multiple searches are treated as AND searches. For example, if you selected an investigation from the pulldown menu of investigations, such as the Bemidji, Minnesota Research Site, and you typed in a year in one of the year text input lines, such as "1994", the resulting search would list references that were published in 1994 related to research at the Bemidji site.
