How much time we spend on social media?

Annotated Bibliography: 1-2 pages, single-spaced, 12-point font.
Directions: Locate 3-5 books and journal articles with useful information on your topic. Briefly cite the books and articles in MLA style. Then, write a concise annotation that summarizes the central theme and scope of the book or article in a single paragraph. Include a few sentences that evaluate the authority or background of the author, comment on the intended audience, compare or contrast the work with others, and explain how the work contributes to your understanding of the topic. Your sources should be listed in alphabetical order by author.

 
Here are some questions to answer in your annotations:
A. Author: What are the author’s credentials–institutional affiliation (where he or she works), educational background, past writings, or experience? Is the author associated with a reputable institution or organization? Is the author’s point of view objective and impartial?
B. Audience: What type of audience is the author addressing? Is the publication aimed at a specialized or a general audience? Is this source too elementary, too technical, too advanced, or just right for your needs?
C. Purpose: What is the author’s purpose in writing the article or book? Does the information appear to be valid and well researched, or is it questionable and unsupported by evidence? Note errors or omissions.
D. Context: Are the ideas and arguments advanced more or less in line with other works you have read on the same topic? The more radically an author departs from the views of others, the more critically you should scrutinize his or her ideas. Does the work update other sources, substantiate materials you have read, or add new information? Does it extensively or marginally cover your topic?
E. Style: Is the publication organized logically? Are the main points clearly presented? Do you find the text easy to read, or is it choppy or repetitive? Is the language free of emotion and bias?
