The Curriculum Collection (PreK-12) has many books with photographs and illustrations. But many other books in the Library are likely to have images, illustrations or photographs. To search for books in the any of the Library's collections, use Research@UWW.
Here are some sample searches. The * symbol will allow you to truncate a word and find any word ending that start with that root. The parentheses will allow you to group similar terms together, using "or" and then combine them with other terms, using "and." Quotation marks will allow you to search for specific phrases.
After doing the search, you can use the Resource Type and Location facets on the left sidebar to limit to specific types of material or locations (you may have to scroll down a bit to see the Locations facet).
