i am doing a works cited for my essay and one of my articles was from wikipedia online. what do i do if i can't find an author?

At the bottom of the Wikipedia page is likely a set of Footnotes or a small bibliography, you may want to search amongst those accredited websites to see if you can find the information and then state the author of that site as the source. As a general rule though, teachers don't usually like Wikipedia because it is an openly editable source of information and as such can often be biased or just wrong, that is unless your teacher has explicitly said that it's ok. Other than that, usually if you cannot find an author for a bibliography in MLA format you can substitute the title of the work or article.

Thanks. I have one more question: How do I cite a page in a textbook?

The same you would any book, it's not a multi-volume work or an encyclopedia so just use the standard MLA format. You shouldn't have any problem finding the author in a well-formed text book.

When citing a page in a textbook in your works cited page, you can use the standard MLA format. Here's how you can do it:

1. Start with the author's last name, followed by a comma and their first name. If there are multiple authors, list them in the same order as they appear on the title page of the textbook.
2. After the author's name, provide the title of the textbook in italics or underlined.
3. Add the edition number of the textbook, if applicable, followed by the abbreviation "ed."
4. Include the name of the publisher, followed by a comma.
5. Mention the year of publication, followed by a comma.
6. Finally, include the page number or range of pages that you are citing, preceded by "p." or "pp."

Here is an example of how the citation would look like:

Author Last Name, Author First Name. Title of Textbook. Edition Number, Publisher, Year of Publication, pp. Page Number(s).

For instance:

Smith, John. Biology: Concepts and Connections. 8th ed., Pearson, 2017, p. 45.

Remember to use hanging indentation for each subsequent line in the citation.

It's important to consult the official MLA handbook or use online citation generators to ensure you are correctly formatting your citations according to MLA guidelines.
