Subject Searching using Library of Congress Subject Headings

The Library of Congress is the authority that controls the vocabulary of subject headings that academic libraries use to organize their collections.  Understanding and knowing subject headings can open up many resources that might not be found through keyword searching.

Subject heading examples:

  • Feminism
  • Feminism and science
  • Feminism and education
  • Feminism and psychoanalysis
  • Feminist archeology

The tricky part is that these subject headings are controlled, meaning that the Library of Congress (LOC) decides what they are and then libraries have to use them.  So it's helpful to know where to find these subject headings. 

  1. If you have a book title that is on the subject you're interested in, search for it in the catalog.  Subject headings will be listed in the book info page. Books can have several subject headings. 
  2. The Library of Congress also has a search feature to explore other subject headings:

  2. Select "subjects" on the right.
  3. Type in your subject.

Now it's just a matter of exploring!
