Difference between Visiting Lecturer and Lecturer? May you please tell me what is the difference between 


  Visiting Lecturer


and 


  Lecturer


Can Visiting Lecturer be considered an affiliation or academic staff, for Ph.D holders?
It surely depends on the circumstances.  

Perhaps in some cases a "Visiting Lecturer" is someone not normally on the staff, who comes for one term or one year and serves as a Lecturer.  After that, going back to their usual job.  

Whereas a "Lecturer" is a regular member of the staff.
