HathiTrust offers two ways of searching their content. A Catalog Search searches a catalog record that lists basic bibliographic information, like title and publisher, as well as information about a book, such as subject terms. A Full-text Search searches the full content of a book, including title, table of contents, the text itself, and any other sections.
Each type of search offers a basic, Google-like keyword search option as well as an advanced search option.
Some general search tips are:
Use quotation marks to look for an exact phrase: e.g., "Alabama Polytechnic"
Use boolean operators (and, or, not) to make your search more specific. "AND" combines search terms ("Alabama Polytechnic" AND agriculture), "OR" looks for either search term (agriculture OR farming), while "NOT" excludes a search term ("Auburn University" NOT Montgomery)
Limiting Search Results
The results page for a Full-text Search and a Catalog Search will look the same. On the left-hand side of the page is a section entitled 'Refine results' with several options for narrowing down the search results. Options for limiting your results include subject, author, language, place of publication, date of publication, original format and original location.
Advanced search allows you to search multiple fields at once. You can also limit your results by full-text availability, publication year, language and original format.
