MLA Style uses the same basic format for all types of sources. Core elements are listed in a particular order, and containers are used when citing a source that is part of a larger work--such as an article within a journal or a chapter within a book.
Which elements get used depends on what is available for that source. This varies by type of source (i.e. journal article vs. book chapter vs. website). The basic format for any citation as described by Purdue OWL is as follows:
If parts of this basic format are not available (such as author or page numbers), omit it and move to the next element of the citation.
DOIs, Permalinks, and URLs are important markers to help your readers find the online materials you have accessed. Be sure to check with your instructor about the inclusion of DOIs, Permalinks, and URLs. Some instructors may prefer you add them to the end of all of your online references, while others may want to keep them out unless they are vital to locating the materials.
DOIs and Permalinks are preferred because they are permanent links to an object's location online. URLs can be changed or broken. However, if no DOI or Permalink is available, use the URL.
MLA does not encourage the use of URL shortening services. Instead, one should drop the protocol (https://) and, if necessary, drop the path if it is overly long, keeping only the host address so readers can evaluate the source and locate the material through their own search on the site.
If you need to break a long URL for hanging indentation, try to do so after a punctuation or symbol (e.g. ., _, /, @)

MLA uses parenthetical citations consisting of the author's last name and the page number, where one exists. If there is no known author, use a portion of the title--which is what appears first in the full bibliography entry.
Fascinating sentence... (Cowley and Shaw 21).
Narwhals use echolocation, like bats, to find food (Mack).
Spary noted... (1052).
