The Random Images button is a great way to just browse the collection. Each Random Images page displays a random assortment of images from the records online. If something interests you, click the thumbnail to view a larger version of the image.
The Keyword Search button allows you to perform a general search across multiple fields for any catalog records online. Keyword searches use OR as the default connector between words (e.g. a search for Forest Service will return records associated with Forest OR Service). If you want to find records where both keywords are found, type AND between the two words. To search for a specific phrase, be sure to put the phrase within quotes (e.g. "Forest Service"). You can also use the asterisk (*) as a wildcard (e.g. a search for histor* would come up with records containing history, histories, historical, etc.).
The Advanced Search button can help you be more specific with your search. You can search for a word or phrase within a particular search category or use multiple categories to further narrow down your search results. For example, searching Smith in the People field will bring up all records of people named Smith. You can also search People and Creator records through Advanced Search. Phrase searching with quotes and use of wildcards (*) are available in Advanced Search.
