The first thing is that the whole Browse the shelf tool works by comparing call numbers regardless of any other data like format or location. It puts all items with a similar call number in one list--as if they were going to sit on the shelf next to one another.
This means that you might find documentary videos (located in our A/V section on level A) interfiled with books on the same subject in the main stacks, along with books from our Juvenile or Ready Reference locations (located on level C and A respectively).
This is a great feature if you want to find other types of materials on the same topic across the collections.
