Shelf-reading is reading each call number (spine label) to ensure that the books are properly shelved. Move through the stacks from left to right and top to bottom. Accuracy while shelf reading is important. When you shelf-read, you will go to a designated stack area and put the books in the correct call number order. The book rows should be made neat by pulling them forward a bit and tightening them up if the rows are loose. Please avoid making rows too tight, which will make it difficult to take a book out or place it back.
