Hints

Library of Congress Subject Headings (LCSH) are made up of a main topic (main heading) and subtopics (called subdivisions), separated by a dash ("--").

Some headings, like "African American male college students" are very specific.  Others, like "Children--United States" are very broad. Such headings will help you gauge the scope and specificity of the book.  A book with a subject heading "Children--Psychology--United States" will be more specific than the book with a heading of "Children--United States."  However, it is possible that each book could have information on children and Internet usage: you would want to check the table of contents and index of the book.  A book with a subject heading "Internet and children" is specifically on that topic.

If a main heading does not have subdivisions, that means it is about that topic in its broadest sense.  Subdivisions (subtopics) tell us that the book focuses on specific themes.

Here are some subdivisions that might be helpful in your research.  You can combine your keywords with these subject terms in the advanced search.

[main heading]--Social aspects [used for topics]

[main heading]--Psychological aspects [used for topics]

[main heading]--Psychology [used for individuals or classes of persons and ethnic groups]

[main heading]--Social conditions [used for classes of persons, ethnic groups, and places]
