Architecture is also a subdivision under topics, cultures, groups, etc. For additional books on your topic, you can also search the online catalogs of other libraries . Once you find references to books or articles elsewhere, you can request the books or photocopies of articles through the Interlibrary Loan Services . The following periodical indexes give you references to articles from journals, books, conference proceedings, as well as book and exhibition reviews.
Updates vary from daily to quarterly.
These indexes are a good source for current articles from popular magazines and newspapers, especially for topics dealing with social and popular issues. Some include full-text and images and are updated daily. Indexes in other subjects may also provide useful information on your topic. If the library does not own that particular journal, you can order it through Interlibrary Loan services. For additional assistance, please ask at the Humanities Reference Desk, level 5.
