Call Numbers, How to Read (Tutorial)

The Robertson Library, like most academic libraries, arranges books on the shelves according to the Library of Congress (LC) Classification System. This system, which uses a combination of letters and numbers, ensures that books on similar subjects are shelved together (making it easier for browsing).

• Materials are shelved alphabetically by the first line of the call number.

• If the first lines are the same, go to the next. This line is shelved in numerical order.

• If the first two lines are the same, then look at the next line. Here the arrangement is alphabetical, followed by decimal order. Some find it useful to add zeros to the decimal in order to create the same number of digits; then read them as you would whole numbers. (.G34 before .G50)
