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:
If a result has the “Full view” option, the work will be available to view, download, search, and add to a collection. Most items will have images of scanned pages and a plain text version.
If the result has the “Limited (search-only)” option instead of a “Full view” option, the volume is restricted and not available for viewing. These items are likely in-copyright and only available to print-disabled patrons. These items still have a "Search inside the text" option that will find the frequency and page number of specific words and phrases, which may help you determine if the work is worth finding elsewhere.
Many works with a full-text view will have the option to download a pdf. This option can be found on the left side of the full-view page of a work.
