re: References on a resume or not?

Don't put references and don't put "References Available Upon Request". Of course they are. Do you put "Drug Test Available Upon Request" or "Interviews Available Upon Request"? After looking at resumes over the years that has become a pet peeve along with World Wide Web proficiency and goofy email addresses.

If somebody asks you for references, put together a summary of a few key references including where you worked together, dates, their role, and a brief statement of how you worked together. Don't send this yet.

Talk to each of your references and tell them about the job(s) you are looking at and why they would be a good fit for your career. Tell them you would appreciate if they would serve as a references. Conceivably they will all agree.

Send each of your references an email thanking them for offering to serve as a reference. In the email, mention a couple of the highlights from the time you worked together, not in a bragging way but just to jog their memory and provide a few talking points (e.g. stuff "we worked on together"). Attach your resume to also jog their memory.

Now send the list of references to the company that asked for them.

All of the above assumes your references are trusted associates and you are applying for a mid-career salaried job, not your burger-flipping buddies referring you for a job at Jiffy Lube. Just my two cents.
