You have to pay attention to the phrasal verb “check out”.
check out (v) = to withdraw (an item) after recording the withdrawal: check out books of a library
The materials cost the library money. Too many people dont want to buy their own books so they will often times not return the books to the library. The only way to maintain the materials and information on who borrows them is to have the items checked out with return dates.
Library materials are checked in and out for a number of reasons. First and foremost so that the library knows who has the item(s) at any time. Secondly, checking an item in and out enables a library to know which items are going out and how often they are.
That little word "of" is important. We take the books out of the library after we check the books out of the library. (Then we take the books home from the library.) The phrasal verb "check out" is in this case a separable phrasal verb.
