In general, limit the use of acronyms as much as possible. Substitutes such as "the center" or "the program" can be used in place of an acronym on second reference.

When using acronyms or abbreviations, spell out the name to be abbreviated on first reference, followed by the acronym in parenthesis. On second and subsequent reference, use the acronym. Do not use periods when writing acronyms.

Example: The Kenneth Langone Athletics & Recreation Center (KLARC) houses the Krebs Family Fitness Center. Gerhard Fieldhouse, which is attached to the KLARC, contains an indoor running track, squash courts and a climbing wall.

If the acronym is not mentioned a second time in the story, then it is unnecessary to include; just spell out the full name on first reference.

Commonly understood acronyms, such as SAT, GPA or NBC (in a story about television networks) do not need to be written out on first reference.

Month abbreviations

Spell out months when used without a numerical date.

Example: Winter break runs from December to January.

When used with a day, abbreviate Jan., Feb., Aug., Sept., Oct., Nov. and Dec. Never abbreviate March, April, May, June or July (the months spelled with five or fewer letters). For more information, see the Numbers, Dates and Time section.

Examples: His birthday is Nov. 29.
Commencement will take place on May 21.

State name abbreviations

State names should be abbreviated only when used with city names, and surrounded by commas. The abbreviation Washington, D.C., should be treated the same as a state abbreviation.

Examples: Princeton, N.J.
The bucolic town of Lewisburg, Pa., is home to Bucknell University.
She was born in Massachusetts.
The White House is located in Washington, D.C., at 1600 Pennsylvania Ave.

For mailing addresses, use the standard address format and state abbreviations (PA, NJ, MA. etc.)

Other than in mailing addresses, abbreviations should follow AP style. Eight states are never abbreviated under AP style: Alaska, Hawaii, Idaho, Iowa, Maine, Ohio, Texas and Utah. The AP state abbreviations for the others are as follows (postal abbreviations are in parentheses).

Ala. (AL)   Md. (MD)   N.D. (ND)
Ariz. (AZ)   Mass. (MA)   Okla. (OK)
Ark. (AR)   Mich. (MI)   Ore. (OR)
Calif. (CA)   Minn. (MN)   Pa. (PA)
Colo. (CO)   Miss. (MS)   R.I. (RI)
Conn. (CT)   Mo. (MO)   S.C. (SC)
Del. (DE)   Mont. (MT)   S.D. (SD)
Fla. (FL)   Neb. (NE)   Tenn. (TN)
Ga. (GA)   Nev. (NV)   Vt. (VT)
Ill. (IL)   N.H. (NH)   Va. (VA)
Ind. (IN)   N.J. (NJ)   Wash. (WA)

Ky. (KY)   N.Y. (NY)   Wis. (WI)
La. (LA)   N.C. (NC)   Wyo. (WY)

Street name abbreviations

The abbreviations Ave., Blvd. and St. should only be used with a numbered address. Do not abbreviate road, drive, terrace or other such terms. Otherwise spell out.

Examples: Judd House is located at 79 University Ave.
Moore Avenue runs through the heart of Bucknell's campus.
His home address is 66 Lexington Terrace.
