A list of references should include the names and complete contact information of three to eight people with whom you currently work or have worked with in the past. The number of references depends on the length of one's work history.
The page should be entitled "References" or "List of References" or "Reference List". For each reference, include name, job title, employer, relationship (if personal), business address, and telephone number with area code. Use only professional references from such people as past and present supervisors and past and current teachers or professors. Use personal references only if you have no other choice.
Never send your reference list with your resume and cover letter unless it is specifically requested that you do so. You should always take your list of references with you in a portfolio to the job interview and give it to the interviewer when requested. Having a prepared list of references makes you look organized and prepared.
