Perform a simple search on "girard" and click on "break down results by decade". The title "Christian pamphlets; Vol. 7" shows up in the decade group "1800s" based--I assume--on a dateIssued of "1800-1856]-1856". On the other hand, the title "Destruction of $150,000, Girard, Ala." has dateIssued elements of both 1900 and 1920, but it does not show up in either of those decade groups. The same situation applies to the title "River of Whiskey".
There are 29 records returned by the original search, but only 27 show up in the decade breakdown. The two titles mentioned seem to be the only ones not accounted for.
