Usually an in-text citation includes only the author's last name and page number. Describe at least two circumstances when you need to include more information to distinguish one author or title from another.

There are two circumstances when more information may be required in an in-text citation to distinguish one author or title from another:

1. Multiple works by the same author: If you are citing multiple works by the same author in your paper, and these works were published in the same year, you need to provide additional information to differentiate them. In this case, include a lowercase letter after the year of publication (a, b, c, and so on) to assign a unique identifier for each work. For example: (Smith, 2010a) and (Smith, 2010b).

2. Multiple authors with the same last name: If you have more than one author with the same last name in your citation, you need to include their initials to avoid confusion. This is applicable when the authors you are citing share the same last name but have different first names. For instance: (J. Smith, 2015) and (L. Smith, 2015).

By including additional information such as the author's initials or a lowercase letter after the year of publication, you can provide clarity and avoid any ambiguity when citing multiple sources or different authors with the same last name.

There are two circumstances when you need to include more information in an in-text citation to distinguish one author or title from another:

1. Multiple authors with the same last name: If there are multiple authors with the same last name, you need to include their initials in the in-text citation to avoid confusion. For example: (J. Smith, 2020) and (M. Smith, 2020) would differentiate between two authors with the last name Smith.

2. Multiple works by the same author: If you are citing multiple works by the same author in the same year, you need to include additional information in the in-text citation to differentiate between them. You can add a lowercase letter after the year to distinguish between the works. For example: (Johnson, 2019a) and (Johnson, 2019b) would differentiate between two works by the author Johnson published in 2019.
