Citing Your Sources

Proper citation is essential. Citing properly allows your reader or audience to locate the materials you have used. Citations give credit to the authors of quoted or consulted information. For detailed instructions on how to cite within the text of your paper, please consult a style manual listed below.
BU Librarians recommend refworks RefWorks as the best tool to manage citations. Accounts are free for the BU community.  RefWorks can automatically create a bibliography in hundreds of styles. Here are some other popular options:
