If you need to find information on an art/architecture/photography subject for research, you can use the databases to find full-text articles.
Caveat: Not all articles are available in full-text. If there's a "full-text" box or search option on the search page of the database then make sure to select it. However, you can try requesting the article through Interlibrary Loan. Learn more here: https://library.shsu.edu/services/ill.html
You can use the Library catalog to limit your search to E-Books: On the Advanced Search page, go to the drop-down menu "Location Groups" and select "Electronic Books", next do your search by keyword, subject, etc. Your results are now limited to E-Books.
TIP: The Library has access to several E-Book collections. Learn more here.
