If you cite a source in your bibliography simply like this:
it does technically indicate where you found it, and someone might be able to find it again. But:
A good citation makes it easy for the reader to figure out the who, what, when, and where of the source. In MLA style, a citation also often indicates how it was accessed.
Identifying the key parts of a citation will help you know how to search for the source. For example:
Author. Title. Title of container (self contained if book), Other contributors (translators or editors), Version (edition), Number (vol. and/or no.),
Publisher, Publication Date, Location (pages, paragraphs URL or DOI). 2nd container’s title, Other contributors, Version, Number, Publisher,
Publication date, Location, Date of Access (if applicable).
If the entire book was written by the same author(s), including the chapter being cited, there will be no book editor(s) listed in the citation.
If the article is available online in a research database, you will often see the database's name and the date of retrieval in the citation, as in the example below. If the article was obtained from a print copy of a magazine or journal, the citation will end with the page numbers.
If the web document has no author or publication date, its citation will not include this information. The "publisher" refers to the organization, company, or other entity on whose website the article or page resides. If the Publisher is the same as the author (e.g. corporate or government author), list it only once.
