Writer Francisco Laguna Correa; poets Michael Dickman and John Sibley Williams; and novelists Deborah J. Ross and David James Duncan are among the university's alumni; Mike Richardson, publisher and founder of Dark Horse Comics, is an alumnus as well. In 2007, Dark Horse donated copies of all of its published works to the PSU Library, which maintains both a browsing collection of book titles, in addition to a research collection which also includes every "print, poster, statue, figure, and all other products."[82]
