Finding Books with Library of Congress call numbers
The Library of Congress classification system groups together books on similar subjects by call numbers beginning with letters which represent different subjects. Library of Congress call numbers are used in the CLTCC BobCat Library.
A list of the main classes of the Library of Congress Classification can be found at http://www.loc.gov/catdir/cpso/lcco/.
Finding a Book on the Shelf
1. Go in alphabetical order. For example, L comes before LA on the shelves. Also note that the more specific the number, the more specific the subject.
Least Specific Most Specific
2. Numbers follow the letters. Search numerically. For instance, 774.5 comes before 774.59.
3. Sometimes the edition (the year of publication of the book) is included in the call number. It will be at the end.
To find a book's call number, search for the book in the catalog. On a book's information page the call number can be found under call number
When you search a database you may learn something about the topic, just from the way the database organizes your search results. Databases are enriched with meta-data-- information about the information-- that makes searching more sensitive, but can also guide you to new ways of thinking about the sources you see in your results. Subject headings and other facet systems can also help you learn more about your research topic.
Vocabulary systems, like the Library of Congress Subject Headings in this graphic, guide you to more precise language and subsets of your topic. In this example of a search for Success, the database gives the user links to search Success in business as well as some narrower aspects of Religious Aspects - Christianity.The subject headings are like categories for discovering and searching more precise aspects of the topic.
As you review the results of your search, subject headings and facets prompt you to ask critical questions about the results. What do I want to know about Hip-hop? What are the social aspects? What is meant by the “religious aspects” of Hip-hop?
