The Sixteen-cent Prexie
Book rate use
The fourth class book rate was eight cents for the first pound plus four cents for each additional pound or fraction thereof from January 1, 1949 until August 1, 1958. The library rate was four cents for the first pound and one cent per additional pound or fraction thereof from January 1, 1949 until January 7, 1968.
This label was on a package mailed circa 1952 by the Kansas State Library, but does not contain the words "Library Rate." The package could have held between two and three pounds of books at the book rate or thirteen pounds of books at the library rate. It could even have held something other than books weighing between two and three pounds at the regular fourth class parcel post rate to zones 1 and 2.
