I found that both the public library as well as the college library (NAU, ASU, PVCC) have some good quality information in electronic form, such as academic journals and/or periodicals. I was amazed at all the articles that were listed in the public libraries database. Good quality sources are also found at universities nation wide. You have to make sure the url is official with an edu in it or it could be considered a source not to cite from. There are also websites created by teachers with quality information in them, but some of these sites require a fee to access or use the information. Rule of thumb is that if the source does not have credible information on it or is not affilliated with an assosiation, university, or other educational entity, you probably dont want to use it for citing as a source in your paper and/or book. You also have to find out if any material you are using is copyright protected and cannot be reposted as your own work. All in all if you dont feel comftorable with the sight your viewing and/or the information, dont use it.
