The Austin American-Statesman ( http://bit.ly/1eEPwOh) reports the letters have been processed and cataloged. They are now part of the center's collection of items related to the secretive author of "The Catcher in the Rye."
Most of the newly acquired letters are written by Salinger to Ruth Smith Maier, a classmate at Pennsylvania's Ursinus College. He and Maier maintained a 40-year correspondence. In one letter the 22-year-old Salinger tells her that while it will take time to convince the public of his writing talents, it will happen.
The letters were purchased from her family for $25,000.
Five letters are written to Ruth Maier's son.
Salinger died in 2010 at age 91.
