Test takers may not access briefcases, handbags, or backpacks of any kind. Hats or hoods, except religious apparel, may not be worn. Sunglasses may not be worn. Books, printed materials, and any notes written before the start of the test may not be used.
Other nonelectronic prohibited items can remain in the room, but they must be put away and not accessed or referenced during the test.
It sounds to me like books are OK if they're just sitting there, e.g. a bookshelf behind you somewhere or on the side of the room--they won't expect you to move the bookshelf away. Just make sure you meet the requirements for what's permitted on your desk:
Generally, your desktop must be clear of anything not test-related and should only have:
Five blank sheets of scratch paper
Valid ID
No. 2 or HB pencils
A highlighter
An eraser (no mechanical erasers or erasers with sleeves)
A pencil sharpener
Tissues
Beverage in plastic container or juice box (maximum size: 20 oz/591 ml). Aluminum cans are not permitted.
