in my paragraph i mention a name of an author on my work cited page. and i talk about his ideas and thoughts etc.

so how do i cite that. just (page number) or do i ever put a citation there.

There are different ways to refer to citations and it is helpful to consult a manual of style. The intent is for the reader to check your references. "...Smith states on page 57 of his book that...." would be one way.

Anonymous is right, and you are right, too. If you put the name of the author in your sentence, then all you need in the citation at the end is the page number. If the work is from the Internet, there are no page numbers, so simply listing the author's name is enough.

When mentioning an author's ideas and thoughts in your paragraph, it is essential to provide a citation to properly acknowledge the source. Simply including a page number is not sufficient. The citation should be placed either within the sentence or immediately following it. Here's how you can cite the author's work:

1. In-text citation within the sentence:
- If you mention the author's name in your sentence, you can include the publication year in parentheses at the end of the sentence. For example:
"According to Smith (2010), his ideas revolutionized the field of neuroscience."

- If the author's name is not mentioned in the sentence, you can include both the author's name and the publication year in parentheses. For example:
"His ideas revolutionized the field of neuroscience (Smith, 2010)."

2. If you want to provide additional information, such as the specific quote or page number, you can incorporate it within the in-text citation. Here's an example:
"Smith argues that 'neuroplasticity is a fundamental concept in understanding brain development' (2010, p. 34)."

Remember to also include the full reference for the author's work on your Works Cited or References page. This page should provide complete details about the publication, including the author's name, title of the work, publication year, and so on, depending on the citation style you are using (e.g., APA, MLA, Chicago).
