Where can I see the standard salary range for California State University Assistant Professor? Is there a website where I can see the standard salaries for recently hired tenure track Assistant Professors in California State University system? I am on the job market and almost in the process of getting an offer. I wanted to get an idea of what to expect and negotiate.

EDIT: it is California State University system.
I'm just assuming you mean California State University since it's the largest system among the states starting with "C", which can be found here:

You can search individuals by name. If the university or university system is public, then the information for faculty/staff salaries is usually posted on some government or independent auditing site.
