The U.S. Department of Labor sponsors a website for job seekers. Whether you are new to the job market or seeking re-employment, this site will be of help.
It offers information on resumes and job interviews as well as information on different careers. There are also links to local WorkForce and Career centers.
Your library also has many books on resumes and job skills. Look in the 650 non-fiction section.
In addition look at the online service that the libraries subscribe to: Learning Express. Sign up for an account using your library card number and PIN (get your PIN from the library.) Learning Express contains information on brushing up your skills in math and writing.
