The University of Idaho Library and the Idaho State Historical Library and Archives have pretty much identical holdings of Idaho newspapers on microfilm. The problem at the U of I last time I was there was that they only had one usable reader/printer. The Historical Library has numerous readers, printers, and scanners. They will also do lookups and copies of obits for a fee - see their website. Or, there are a number of people who volunteer to do this sort of lookups. The old Random Acts of Genealogical Kindness site has gone away, but there are four or five other sites using more or less the same concept.
