Is this passage plagiarized? I think so, because only the author's name is given and not the page number in the in-text citation.

"...fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal." (Lincoln)

No. Further citation is not needed for anything as well known as these words from Lincoln's Gettysburg Address.

What about this one? It isn't as well known.

"No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature." (Stevenson)

"No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature." (Stevenson)

not plagiarized because you have the name Stevenson and you have quotations to signal that someone else said it. It may not be a fully correct citation since it doesn't have page number but it should be okay.

To determine whether or not this passage is plagiarized, you need to gather more information and evaluate the citation provided. Plagiarism refers to the act of using someone else's work or ideas without giving them proper credit.

In this specific case, the citation includes only the author's name, Lincoln, without any page number. The absence of a page number could suggest that the passage has been copied without proper citation or attribution. However, it's important to note that the evaluation of plagiarism requires more than just the format of the citation. It also depends on the context in which the passage is used and whether or not the original author's work has been properly credited.

To confirm if this passage is plagiarized, you can take the following steps:

1. Identify the source: Try to determine where the passage originated from. Is it from a specific book, article, or speech? By identifying the source, you can then verify the accuracy of the citation.

2. Research the original source: Look up the original source attributed to Lincoln and compare it with the passage in question. Check if the words match exactly or if there are any alterations made.

3. Evaluate the citation: Determine if the citation is correctly formatted and includes all the necessary information. In academic and formal writing, a proper citation should include the author's name, the year of publication (if applicable), and the page number (if applicable).

4. Assess the use of quotation marks: If the passage is a direct quote, it should be enclosed within quotation marks. In this case, if the passage is taken verbatim from Lincoln's original work, it should be indicated with quotation marks.

5. Consult relevant plagiarism guidelines: Refer to the guidelines provided by your institution or organization to understand the specific standards for citing sources and avoiding plagiarism. Different contexts may have slightly different expectations.

By following these steps and considering the context and citation format, you should be able to determine if this passage is indeed plagiarized.
