The Advanced Search function allows for specific searches including various fields, including keywords, caption, search terms, catalog number, lexicon category or sub-category, description, and by date. Use the Advanced search feature for directing specific searches. One example would be to search for steel workers during the 1950s. Put "workers" as a search term, "steel" in the description, "1950" as the start date, and "1960" as the end date. Click "Search" at the bottom of the page to see the results.
