Giving credit to a book, article, speech or other resource is called citing or creating a citation and is required to avoid plagiarism. Your instructor may ask you to cite in MLA, APA, Chicago, or other formats.
A citation generator will apply the appropriate formatting and punctuation to your bibliography information to make it easier for your reader to look up the source you used. These are all pieces of information you may need to create a citation:
Title of the Source
Title of the Container
Other Contributors (editors, illustrators, translators)
