Hi.  I'm researching a locality in mindat called Crystal Peak in La Paz County, Arizona.  The mindat locality shows several references.   I've tried to research the first two references (shown below)  and I can't seem to find them in the digital library and I also have been unable to find them in electronic format on the internet.  Perhaps I'm using the library incorrectly, or perhaps the references are available electronically.  Does anyone have any insights or other ideas?  Thank you.
