"Онабра ла ту книжку из библиотеки."

Это означает ли "Она отдала ту книжку в библиотеку" т.е. "та книжка уже у ее нет" ?

A couple of reference books say she took the book from the library and returned it back to the library because of the imperfective verb.

But as far as I heard, sometimes yes and some times no, namely, she may still keep the book.

What is the correct answer?
