Primo is a library search tool for finding materials in the Collins Library and Summit libraries. You can search for books, selected articles and more in a single search box.

• Use the pull-down scoping options to search Collins, Summit and Articles OR Collins and Summit, OR just Collins.
• Use quotes to search for "exact titles".
• Use the filters on the right side to quickly narrow your search.
• Sign in with your Puget Sound username and password to gain access to online resources and request items from other libraries.

Books in Primo are assigned Library of Congress Subject Headings.  In many ways, subject headings are a form of tagging, in that they represent the content of the material and provide ways for you to efficiently locate more materials that are conceptually related. 

Here are several examples of the various ways you can use LCSH to help pinpoint what you need:

Wilderness areas -- West (U.S.)

Northwest, Pacific -- History

Northwest, Pacific -- Environmental conditions

Human ecology -- United States -- History

Nature -- Effect of human beings on -- United States -- History

 A sampling of potentially relevant books is listed below. Some titles available in print and in online format. 

Collins Library uses the Library of Congress classification scheme to organize books on the shelves. Follow these tips to find the book you need.

Example:

• Start with the top line. It is in alphabetical order. Ex. E
• The second line is a whole number.  Ex. 169.1
• The third line is  a combination of a letter and numbers. Read the letter alphabetically. Read the number as a decimal, eg. Y.23, Y.34, Y.344, Y.4, etc. Ex. .N37 (*Some call numbers have more than one combination letter-number line.)
• The last line is the year the book was published. Read in chronological order. Ex. 2001, 2005, 2010, 2015, etc. Ex. 2001

Use the library map to find where the book is located.
