In-text citations are also called parenthetical references -- you can remember because the parenthetical reference is in parenthesis.
MLA uses author-page style. In your paper, you will use the author's last name and the page number of your quote. You will use the last name in either the sentence or in the parenthesis.
You can see both in use below:
"Our personalities are masks we wear to sell ourselves to others" (Berger 87).
In Ads, Fads, and Consumer Culture, Berger states "Our personalities are masks we wear to sell ourselves to others (87).
The first word in the bibliography entry will usually be the word (name) that goes in the parenthesis.

In a slide-based presentation using software such as PowerPoint or Keynote, we suggest including brief citations on each slide that uses borrowed material (quotations, paraphrases, images, videos, and whatever else you copy or adapt) and adding a works-cited list on a slide at the end.

In a video, you might overlay text at the bottom of the screen to provide your viewers with brief information about what they're seeing (the producer and title of a borrowed video clip, for instance, or the name of a person being interviewed) and include full documentation in your closing credits.
In a project on the Web, you might link from you citations to the online materials you cite, allowing a reader to follow references of interest. A works-cited list remains desirable as an appendix to the project, since it gives the reader an organized account of the full range of your sources.
Give the author's last name either in the text or in the parenthetical. Put the page number in the parenthetical.

Examples from OWL:
Citing two articles by the same author:
Visual studies, because it is such a new discipline, may be "too easy" (Elkins, "Visual Studies" 63).
These are "quoted in" citations -- you have not looked at the original source but a source that quotes the original.
You will use qtd in before the author and page number.
