The abstract submission deadline was September 19, 2012.
Abstract submission is handled via the APS Abstract submission site. Click on this link to access the site (make sure cookies are enabled on your browser). From there, select "Start Abstract Submission" and then select the box beside "14th Annual Meeting of the Northwest Section of the APS" from the list and scroll to the bottom of the page to continue with your submission. Both LaTeX and RTF formats are accepted. This website will work for abstracts from both APS members and non-members.
PLEASE NOTE: You still have to register for the conference after submitting an abstract. This can be done via the "Registration and fees" link.
