Only capitalize the first word in a book or article title. Unless they are the initial word of the title, articles (i.e., a, and, the) should not be capitalized. Italicize the titles of journals and books. Do not use quotation marks around article titles.
Journal, magazine, and newspaper titles should be italicized. Article titles should not be italicized. Only capitalize the initial letter of the article title's first word. All other words should be lowercase.
The New York Times, The Washington Post, and The Boston Globe are all titled journals in the American Psychological Association (APA) format. They should be cited with initials in parentheses after the publication name: Journal of Applied Psychology or Journal of Experimental Social Psychology. If the reference is to an entire issue, include the date of publication at the end of the citation: vol. 92, no. 3 (March 2009).
Newspaper titles should not be italicized. However, if they are printed in small typeface or within quotation marks, then they should be entered into the text as regular sentences but should be referred to by using caps lock: CAPS LOCK! THE BOSTON GLOBE IS A NEWSPAPER.
Journal, magazine, newspaper, and book names should be italicized. It is not necessary to italicize the titles of articles or book chapters. If the article title contains a colon, capitalize the initial letter of the first word after the colon. Book titles are usually given without italics.
In a title, capitalize proper nouns, initials, and acronyms. A colon and a space should be used to separate a subtitle. These elements should not be capitalized.
Book titles are usually written in italics. However, if you are using a typewriter typeface instead of italic type, then book titles would not appear in italics. On the other hand, if you use italics instead of a typewriter font, then book titles will appear in italics.
Article titles are usually written in caps. However, if you are using a typewriter typeface instead of caps, then article titles would not appear in caps. On the other hand, if you use caps instead of a typewriter font, then article titles will appear in caps.
The title of a website, including its domain name, web page titles, and sub-page titles, should be written in caps. Although this is common practice for websites, it is not required by any standard. Some web browsers may not distinguish between small capitals and regular capitals, so words should be set in mixed case to ensure that they are treated as such.
This is only true for books, articles, and websites that were created after 1990.
Newspapers or magazines Unless it's part of the publication's title or masthead, don't uppercase "magazine." The word "the" should be capitalized only if it appears in the title of the magazine.
If the source is self-contained and independent, italicize the title. Italicizes the titles of books, plays, films, magazines, databases, and websites. If the source is part of a larger work, put the title in quotation marks. Articles, articles, chapters, poems, websites, songs, and speeches are all surrounded by quote marks.
In most cases, the title of a work is preserved exactly as it appears in the publication. Do not use periods at the end of sentences when citing sources in an academic paper.
Capitalization matters because some words are treated differently by computers. For example, "the" and "a" appear in most file formats but "THE" and "A" do not. So, including capital letters where necessary can help computers read your documents correctly. And since many academic papers are now published online only, readers rely on software to find appropriate sources. So ignoring small details like this could mean that important information is missed.
There are two types of titles: descriptive and formal. Descriptive titles are usually short phrases such as "A History of Art", "Psychology's Place in Science", and "18th Century France". Formal titles are longer than one sentence and often include the name of a person or organization along with a description of what they did. For example, a study might be titled "John Doe improved painting techniques in 18th-century France".
In general, follow the rules given here. If in doubt, refer to other works by the same author or company.
How to Capitalize Titles Properly
All main terms in journal names should be capitalized. Titles of lengthy works, such as books and periodicals, should be italicized. Italicize, underline, or quote titles of shorter works, such as journal articles or essays in edited collections. Capitalizing the title of a work is usually done to distinguish it from other works by the same author or editor with the same or similar title. Title capitalization can also identify authors in cases where only part of their name is used as a reference (for example, John Smith). In this case, the entire title should be capitalized.
In general, follow standard book publishing practice and capitalize only the first word of the title, unless it is an acronym (initialism), proper noun, or brand name.
Acronyms are words or phrases formed by combining letters or numbers (such as MRI for magnetic resonance imaging). When used in titles, they should be capitalized because they function like words. For example, "MRI-safe knives" would be incorrect because it is not clear whether "MRI" is an acronym for something.
Initialisms are words or phrases that start with the same letter (as in "post-modern"). They too should be capitalized because they function like words. Thus, "post-modernism" is correct while "Post-modernism" is not.
