Hints for searching: 

      Try spelling out business names.  NCR, for instance, was usually referred to as National Cash Register. 
      Those looking for the VA Center, also known as the Soldiers' Home, should also try National Military Home, or National Home, or Disabled Volunteer or just Military Home.  Be sure to try Soldiers' Home with and without the apostrophe after the s in Soldiers.  If you want to find an exact phrase, place the words in quotation marks, like "National Military Home". If you are patient and try other combinations of words, sometimes the rewards are worth the hassle.
