A man accused of checking out hundreds of books and DVDs from libraries around the Denver area and then trying to sell them will be doing all his library borrowing from now on behind bars.

Denver prosecutors say 34-year-old Thomas Pilaar was sentenced to 10 years in prison and ordered Tuesday to pay $53,549 in restitution. He pleaded guilty in May.

Of an estimated 1,400 books and DVDs that were taken, about 500 have been recovered.

Denver Public Library estimated it had lost $35,000, while Douglas County said it had $11,000 worth of overdue items.

Authorities were tipped off by a woman who recently bought books on Craigslist and noticed the library identification stamps.
