Wikipedia is a great resource for getting general info about something, but because anyone can contribute or change its content may not be considered entirely reliable. College faculty typically do not consider Wikipedia a credible information source.

A dictionary of food and nutrition
Handbook of Safety Principles
The Midwife's Labour and Birth Handbook by 
The Wiley-Blackwell Handbook of Addiction Psychopharmacology
