Wikipedia can be a good resource for getting general info about something, but because anyone can contribute or change its content, it is considered unreliable. College faculty typically do not consider Wikipedia a credible stand-alone information source.
You can turn directly to the sources referenced at the bottom of most Wikipedia entries, to get more detailed information about the nuances & historical items of interest that were summarized by Wikipedia.
You can also supplement or verify the information found in Wikipedia by using the library's print or electronic encyclopedias, dictionaries, or other reference books to backup the basic information of your research paper. These library oriented resources have gone through an editorial process to check for accuracy.
