DENVER -- A library patron suspected of selling hundreds of books, tapes and DVDs he had borrowed has cost Denver-area libraries tens of thousands of dollars, officials said.
Thomas Pilaar, 33, was suspected of using different names to obtain seven library cards from the Denver Public Library, then checking out 300 items per card and selling at least some of the items, KCNC-TV in Denver reported.
"It appears his intent was to sell 2,100 (items) from the Denver Library collection," Denver Public Library spokeswoman M. Celeste Jackson told the station. She estimated the losses at about $35,000.
Arapahoe County library administrators said Pilaar obtained three library cards and checked out 250 to 300 items.
James Larue, Douglas County's head librarian, said Pilaar checked out more than 300 items from two county libraries and had $11,000 worth of overdue items.
Authorities were tipped by a woman who recently bought books through Craigslist.org and noticed the library identification stamps.
