The UNT Libraries currently use the Library of Congress system to classify the books in our collections.
The Library of Congress system uses both letters of the alphabet plus numbers to classify books. Classification causes books on similar topics to be together on the shelves.
For most fields, the letters in call numbers have nothing to do with the names of the topics in question. Music is one of very few exceptions.
The two kinds of call numbers for music books are ML and MT. ML stands for music literature, while MT stands for music theory or music teaching.
PLEASE NOTE: Many of our music education books have MT call numbers. If you are interested in browsing, MT 1-MT 18 is a good area to visit.
Most of our instrumental and vocal method books have MT call numbers as well.
Call numbers beginning with the letter M by itself are for music scores. Some method books have M call numbers.
The call numbers assigned to the CDs in the audio center are local numbers we created here. They begin with LPCD. These numbers do not classify CDs; the next CD we add to our collection gets the next LPCD number.
Most of our print journals do not have call numbers. Instead, they are shelved in alphabetical order by journal title. There are a few exceptions, however. Annuals, or journals only published once a year, usually have call numbers. Thus, if you are searching for a journal by title on the shelf and cannot find it, look it up in the catalog. It may be one of the annuals, and you will need to look for it under its call number.
