Abbreviations

Many abbreviations are followed by a period.

Personal Names

Abbreviate names if a person is commonly known by the abbreviated form of the name. Place a period after each initial, leaving a space between two initials, but not between three or more.

EXAMPLES 

• Thomas A. Edison 
• Ida B. Wells-Barnett 
• T. S. Eliot 
• M.F.K. Fisher

Titles

Abbreviate social titles (Mr., Mrs., Ms., Sr., Sra., Dr.) whether they are used before the full name or before the last name alone. Abbreviate civil and military titles used before full names or before initials and last names. Spell out civil and military titles when they are used before last names alone. 

EXAMPLES 

• Dr. Michelle L. Rodriquez [Social titles are abbreviated.] 
• Sen. Mary Janowitz [Civil titles are abbreviated before full names.] 
• Prof. J. Garcia [Civil titles are abbreviated before initials and last names.] 
• Senator Thomas [Civil titles are spelled out before last names alone.]

Abbreviate titles and academic degrees that come after names.

EXAMPLES 

• John Andrews, Jr. 
• Janet Meyerson, M.D.

NOTE

Do not use the abbreviations Mr., Mrs., Ms., or Dr. with a title or degree that appears after a name.

INCORRECT 

• Dr. Robert Agarwal, M.D. 

CORRECT 

• Dr. Robert Agarwal 
• Robert Agarwal, M.D.

Agencies, Organizations, and Acronyms

Many agencies and organizations are known by their acronyms. An acronym is formed from the first (or first few) letters of a series of words. When writing, spell out the first use of the name of the agency or organization. After that, you may use the acronym. Do not use periods in acronyms.

EXAMPLES 

• PBS
  Public Broadcasting Service 
• HSUS
  Humane Society of the United States

Geographical Terms

Spell out names of states and political units in regular text. Abbreviate names of states and political units in tables, notes, and bibliographies.

• TEXT
  Have you ever been to Portland, Oregon, or Memphis, Tennessee? 
• TABLE OR NOTE
  Portland, Ore.
  Memphis, Tenn.

Spell out the words of an address in regular text. Words in a letter address or in tables and notes may be abbreviated. Use two-letter state abbreviations only when the ZIP Code is included.

• TEXT

Time

Always abbreviate A.D. (anno Domini), B.C. (before Christ), A.M. (ante meridiem), and P.M. (post meridiem). Spell out the names of months and days in regular text. The names of months and days can be abbreviated in tables, notes, and bibliographies.

Units of Measurement

Spell out the names of units of measurement in regular text. They may be abbreviated in tables and notes following a number. Abbreviations for units of measurement are usually written without periods, but in., the abbreviation for inch, always has a period to avoid confusion with the word in.

• TEXT

• TABLE OR NOTE

  1 doz eggs [Abbreviated measurements are written without periods, except for in. for inch.]
