When we set up a Google Scholar profile for the collection about a year ago (see a note on this here and our methods in creating it here), we began to pay more attention to publications that had cited articles that the bird collection had directly contributed to in some way. You might think of these as second-generation contributions accumulating downstream from the direct use of this collection. Usually, these once-removed, downstream uses are papers on familiar subjects, contributions to the science of birds or to evolutionary biology and zoology.
But imagine our delight to come across a wonderful paper by Dr. Debby Herbenick and colleagues entitled “Erect Penile Length and Circumference Dimensions of 1,661 Sexually Active Men in the United States”.
