Welcome to the College of the Siskiyous Library!

The Library is here to help you throughout your time at COS.
Check out our online materials or visit the library for a comfortable quiet place to study.

The Library's hours are Monday - Thursday 8 am - 5 pm and Friday 8 am - 2 pm.

For the month of October, the College of the Siskiyous Library would like to offer our services to the Weed Community which has lost its public library in the Boles Fire. During this time of reorganization, Weed Community members can show their public library card or a picture ID showing residence in Weed to request guest use of computers, internet access, and printing. People under the age of 18 who want to use the computers need to be accompanied by a parent/adult. For more information, please contact the COS Library at 530-938-5331 or

October is National Breast Cancer Awareness Month. Think Pink!

Students, remember to request your Library Card!

The Catalog allows you to search the Library’s collection of books and media items, as well as search for ebooks, full text articles and streaming video. To use ebooks, online articles or streaming video from off-campus, you will need your library card barcode number and account password.

Want to learn about using the Library’s Catalog and databases? Stop by the Library for one-on-one help, visit our How Do I…? page, or attend one of the Library’s Student Success Seminars being offered throughout the semester. Look for “Library Research Basics” and “Tips & Tricks for Database Searching” on the schedule.
