Most searchers rely exclusively on keywords to retrieve records in online catalogs. If you wish to retrieve more precise results, try searching by controlled vocabulary for your topic, often referred to as "subject headings" or "descriptors."
For example, the Library of Congress subject heading for art education is "Art—Study and Teaching."
Books remain important to the disciplines of art, architecture, interior design, and landscape architecture.
If we don't own the book or have access to an online version, request it via the Libraries' Interlibrary Loan (ILL) service, ILLiad.
If our collection lacks something critical and obtaining via Interlibrary Loan is unsatisfactory in the long term, contact me and I can attempt to purchase it. You still may wish to place the ILL request—even if money is available, it takes time to purchase and process a text.
