Keyword Search gives access to items and exhibits in the Maine Memory Network. Type in a keyword, phrase, or document number (MMN Number) and specify whether you would like to search by the exact word or similar words.

When your search results are either too specific or too broad, you can use a Logical Operator (also called Boolean Operators, or Boolean Search Terms) to modify your search keywords. Logical Operators are linking-words like AND, OR &, NOT, which combine the search criteria in various ways to narrow or broaden a search.
Enter Logical Operators between keywords in the keyword search. The operators are case sensitive -- USE UPPERCASE ONLY.
"shipbuilding AND Bath NOT navy"
retrieves first the items or exhibits that contain both the words "shipbuilding" and "Bath"; then among those, it retrieves the ones that do not contain the word "navy".
Without these operators, the search engine will assume you're putting the term AND between each search term. The minus sign can also be used in place of NOT.

Searching for similar words is the default search. You should switch to "exact word matching" when an initial search returns too many results.

Once search results are returned to you, you have the option of conducting successive searches within those results. At the top of every search page is a search box where you can select "search within these results" (performs new search within returned results) or "new search" (performs new search from scratch).

The Browse by Topic section of the search page contains fifteen browse headings, ranging from Arts & Entertainment to Transportation. These headings are underlined and are in bold text, and each heading has a partial list of subcategories under it. If you click on any of the major browse headings, you will be taken to a search results page specifically for that heading. Clicking on any of the subcategories will automatically return a search for that subcategory.
