Advanced Search is useful when you need to use more than one search term or need more detailed search options than those offered in Basic Search. Advanced Search lets you:
Search the catalog using multiple key phrases
Filter by date, language, and format
Choose to include or exclude government documents and HathiTrust eResources
To do an Advanced Search, start by clicking the Advanced Search link under the search bar in the Library Catalog:
Multiple Search Bars
Advanced Search gives you four different search bars where you can search by keyword, title, author, subject, or ISBN/ISSN.
You also have the option of changing the Boolean operators on the far left to either narrow (AND/NOT) or broaden (OR) your search. For more information on Boolean operators, check out this MIT Library Guide.
Filters allow you to make your search as narrow and targeted as possible so you can find exactly what you need. In the library catalog you can filter by:
Version (e.g., if you're only looking for the e-book of the title)
Format (e.g., if you were only looking for a music recording or video)
You can select multiple dates and languages by holding down the CTRL key. To search for a specific publication year, use the text box near the list of dates.
To search by format, check the boxes next to the formats you would like to search.
