Here are some more useful resources for dealing with human protections/IRB issues:

• The Belmont Report (Guidelines and recommendations that gave rise to current Federal regulations)
  
  
• Federal Regulations Regarding Protection of Human Research Subjects (45 CFR 46) (Also known as the "Common Rule")
  
  
• Federal Office for Human Research Protections (OHRP)
  
  
• NIH Human Participant Investigator Training (Although the site appears to be for cancer researchers, it is the site for the general investigator training used my many institutions)
  
  
• University of Minnesota Web-Based Instruction on Informed Consent
