Mamet, 59, said he was pleased.
"Having an archive in the care of the Ransom Center, in the care, if I may, of intelligent and dedicated enthusiasts, fulfilled both the fantasy of the parent, and that of the artist, who now, though absent, might envision a cost-free colloquy with a perfect interlocutor," said the Pulitzer Prize-winning playwright who earned two Oscar nominations and a Tony Award nominations.
The collections includes more than 100 boxes, the university said in a news release, containing manuscripts, journals, office and production files, correspondence and drafts of Mamet's works -- including the plays "American Buffalo" and "Glengarry Glen Ross"; screenplays "The Untouchables," "The Spanish Prisoner" and "Wag the Dog"; and unpublished or abandoned works.
Mamet agreed to participate in several residencies for four years.
The university didn't disclose the purchase price. Ransom Center Director Tom Staley told The Austin (Texas) American-Statesman the collection cost in "the million dollar range."
