MLA 9 uses a Works Cited list which is an alphabetical list of all the sources you specifically called out in your assignment. A Works Cited list belongs at the end of your assignment under the header Works Cited. A Reference List (or References) is a very similar term used when using APA to format your references.

A bibliography is different in that you can list all sources you consulted even if you do not directly call them out in your assignment. 

The terms referencing and citing are often used interchangeably but do mean different things. The citation is the acknowledgment of the source in the text (your assignment) that points your reader to the reference. The reference provides the information a reader would require to track down that source.
