Library of Congress Subject Headings are used to provide subject access to books in most U.S. libraries.

Dewey organizes knowledge according to a conscious western philosophical structure. While the Library of Congress system uses a structure that has a western bias, it is much more pragmatic in its approach. Both systems group material together into subject areas so that like items shelve next to each other.

Library classification systems attempt to shelve books together by subject. This is because organizing books based on subject allows for easier navigation and retrieval of information. It ensures that books on similar topics are grouped together, making it convenient for users to locate relevant materials. By categorizing books according to subject, libraries can create a systematic arrangement that promotes efficient browsing and research.

It is very difficult to update and make changes to library classification systems. Any change made to a classification system impacts the libraries using the classification system. To keep up with the changes in a classification system a library must identify all the items affected by the update and reclassify the items to reflect the change. This can add a significant amount of extra work for library staff. As a result library classification systems are very conservative in making changes.

The two major classification systems used by libraries in the United States are the Dewey Decimal Classification System and the Library of Congress Classification System. The Dewey Decimal Classification System is a numerical system that categorizes books based on subject matter, while the Library of Congress Classification System uses a combination of letters and numbers to classify books based on subject matter and author. Both systems are widely used in libraries across the country to organize and locate books.

The Dewey Decimal Classification System starts with numbers and divides knowledge over 10 broad categories.

Classification systems are designed by human beings in a specific culture at a particular time in history. As a result they contain bias. Although the people who create the classification system (usually librarians and indexers) try to be as objective as possible, no one is completely objective. Therefore all classification systems are subjective to a certain extent and contain bias. Because there is no way around this, you should become aware of a classification system's bias and work with it accordingly.

Periodical indexes tend to create their own subject headings rather than use the Library of Congress Subject Headings. LC Headings are often not adequate for the needs of periodical indexers.

Most books and periodical articles receive more than one subject heading because most books and articles cover more than one subject. By assigning multiple subject headings, librarians ensure that the item can be found by different searchers who may be looking for it under different subjects. This increases the chances of the item being located by a wider range of users.

All three answers are true and contribute to the difficulty in cataloging and indexing information.
