Final answer:
The given citations reflect elements of MLA formatting, highlighting the author, title, publisher, and access date. However, for full adherence to MLA guidelines, the citations would typically also include URLs or DOIs if available, and newer MLA standards no longer require the use of the city of publication for modern sources or 'Web' as an indicator.
Step-by-step explanation:
In accordance with MLA guidelines, the properly formatted web source citations must include certain core elements such as the author's name, article title, website title, publisher or sponsor of the site, original publication date if applicable, and the access date. Also, when formatting the citations, they should be listed in alphabetical order based on the author's last name or the first word of the citation if there is no author. The given citations each reflect elements of MLA formatting, but for full adherence to the latest MLA standards, they would commonly include the URL or a DOI if available, although this is not strictly shown in the examples provided. It is also worth noting that the requirement for the city of publication has been omitted in the 8th edition of MLA for sources published after 1900, as well as the use of 'Web' as an indicator of online sources, which is no longer recommended. However, these citations do reflect some of the practices prior to the most recent updates to MLA guidelines.
The use of an access date is optional but recommended, especially if the digital content is subject to change or if the instructor requires it. The access dates are present in the sample citations and are placed at the end of the citations.
