Call numbers are used to organize books on shelves by grouping similar books together. Call numbers beginning in GV are shelved in Rose Library. If you wish to explore the books we have about choreography for example, you would go to books on the shelfs labeled GV 1782.5.
Many eBooks are also assigned call numbers, but of course they're not on the shelf. To see both the printed books and eBooks in a call number range, use the Browse by Call Number feature in Library Search as demonstrated in the video below. Another way to browse is to use the Virtual Browse panel at the bottom of most book records as demonstrated in the below video.
Subject headings are descriptions of the content of library materials using precise language.
In the library catalog, books, videos and other materials are assigned subject headings based on their content. Here is a sample list of theater-related subject headings. When you view catalog records in Library Search, these subject headings are links to other items with the same subject.
This is not an exhaustive list, but it should give you a sense of commonly used vocabulary and how subject headings are structured.
