Scientific journal articles are on overlooked source of numismatic information. Craig Sholley and others have used sources such as the Journalof the Franklin Institute to shed light on various technical issues within numismatics. The Newman Portal has recently extracted articles fromScientific American dealing with coins and paper money, and these are now available on Newman Portal.

An article in April 1850 issue, for example, discusses the closure of the New Orleans Mint for administrative reasons - no one cared to apply forthe open Treasurer position due to the lack of salary and the size of the bond required. Elsewhere, the February 1876 issue discussed protection ofbank vaults. In total, approximately one hundred articles have been pulled and these provide an outsider's view of American numismatics from anestablished and respected source.
