The author field limits your search to publications by certain authors.
Only last names and initials are in the data base—Lastname, F.M.
Standard USGS bibliographic format is used.
For more than one author you can select one of the radio buttons to search for either all the authors (LeBlanc AND Harvey), either author (LeBlanc OR Harvey), or a phrase (a literal string – "LeBlanc, D.R., Garabedian, S.P."). Quotes are not needed for phrase searches.
