Wikipedia is a helpful and interesting tool. But it is not considered a scholarly resource. Its OK to use Wikipedia as a starting point if you don't know anything about a topic, but don't rely on this website for your academic work.
If you need an introductory resource to help you understand a concept try a textbook - really! A book published by a reputable scientific publisher has undergone some kind of peer review or editing process prior to publication. Or you can use a professional resource like UptoDate.
The library has a great collection of print and ebooks to help you in your professional studies. To see what resourcse are available search the library catalog.
