Editorial Style Guide

Just as the university strives for consistency of communication design, it also encourages clarity and consistency in its messages. Our audiences oftentimes overlap; the parent of a prospective student could also be a graduate, a legislator, a donor or an employer of our graduates. The Iowa State materials received by that one person could come from admissions, the alumni association, his or her college, governmental relations, or one of the college career services offices. It is important that we all treat language, punctuation, and grammar consistently and clearly.

The Chicago Manual of Style and The Associated Press Stylebook provide the foundation for this guide. Strunk and White's The Elements of Style is also a resource.

Use this guide to help you write anything intended for the campus and external audiences. If you are doing technical or academic writing, some of these guidelines may not be appropriate.

Iowa State University Specific Guidelines

When writing about Iowa State, use Iowa State University first and follow with Iowa State. Avoid using ISU if at all possible, due to the potential confusion with Illinois State University, Idaho State University, and Indiana State University. Lowercase university when standing alone.

Iowa State University of Science and Technology is the official name of the university.
The university is organized into nine colleges.

Abbreviations

For the most part, avoid in running text (Professor Johnson, not Prof. Johnson). Use only where clear to readers. Normally spell out at first occurrence, unless it is almost never used in spelled out form (such as DNA, GOP).

Academic and administrative titles

Capitalize titles when they precede names and are used as part of the names. Lowercase if they follow names or are used to further identify people. In lists such as those used in programs, titles are usually capitalized even when following names.

Professor John D. Hancock
Gregory L. Geoffroy, president of the university
Well-known professor of psychology, John H. Jones

If a title contains the full name of an academic or administrative unit, capitalize the unit name.

John D. Hancock, professor in the Department of Psychology, ...
Jane Doe, a secretary in the Office of the Registrar, ...

For consistency in publications, the Office of the Provost has approved the following style for professors and instructors.

professor of mechanical engineering (for full, associate, or assistant professor)
instructor in mathematics
The provost's office notes one exception. There is no of used with the library.
It is professor, library.

The following style is for endowed chairs, named professorships, and distinguished professorships.

John James, Distinguished Professor in the College of Liberal Arts and Sciences and professor of zoology and genetics
John B. Jones, A. B. Martin Endowed Chair in Plant Pathology
For named professorships, cap all nouns in the title, whether the title appears before or after the person's name.
John A. James, the Albert C. Jones Professor of History

Academic colleges

Iowa State has eight colleges, including the Graduate College.

College of Agriculture and Life Sciences
College of Business
College of Design
College of Engineering
College of Human Sciences
College of Liberal Arts and Sciences
College of Veterinary Medicine
Graduate College
Uppercase college when used as part of the proper name of a college; lowercase when used alone or with an unofficial name, whether it refers to a specific college or not.
She is a student in the College of Engineering.
John is a senior in the engineering college.
There are more than 5,000 students enrolled in the college.

Academic degrees

In general, do not use abbreviations for degrees after a personĂ¢â‚¬™s name unless it is necessary to establish credentials. Do not include the word degree after a degree abbreviation.

He has a B.A. in history.
not He has a B.A. degree in history.

Don't use Dr. with the degree designation. Use either Dr. John Jones or John Jones, Ph.D.

Common practice is to use periods without spaces for abbreviations of degrees (B.A., M.S., Ph.D., M.Eng., M.B.A., LL.D. and LL.M.). The most recent edition of The Chicago Manual of Style, however, recommends omitting the periods unless required for consistency or tradition.

Degree abbreviations are best used in listings, while spelling the degrees out is more readable in regular text.

associate degree; baccalaureate degree, bachelor's degree and master's degree; doctoral degree, doctorate (don't follow doctorate with degree); bachelor of arts, master of science, doctor of philosophy.

Set off degree names by commas when they follow personal names.

Mary Jones, master of science in biology, is the coordinator of the program.

Academic year

fall semester, spring semester, summer session—no caps when used to refer to time of the year.

Acronyms

Try to avoid. Universities overuse acronyms and incorrectly assume that its publics have high awareness of what the letters stand for and an understanding of what the organization does. Acronyms only confuse. Exceptions are widely recognized acronyms such as NASA, SAT, ACT, FBI.

Adviser/Advisor

Adviser is the preferred spelling.

Alumna, Alumnae, Alumnus, Alumni

Alumna refers to one female graduate. Alumnae refers to two or more female graduates. Alumnus refers to one male graduate. Alumni refers to more than one male graduate or a group that includes both female and male graduates.

Ames Laboratory

On first reference, always use Ames Laboratory. On the second and subsequent references use Ames Lab. When a formal declaration is needed, use U.S. Department of Energy's Ames Laboratory.

The use of chair is preferred.

Company names

In running text, company names are best given in full form. Abbreviations such as Inc. and Ltd. can be omitted unless they are relevant to text. If used, commas are not required around the abbreviations.

Home 515 555-5555
Office 515 555-5555
Fax 515 555-5555
(Note that university style is without the hyphen between the area code and 7-digit phone number.)

When listing mailing addresses, use the two-letter postal abbreviation for the state. In running text or if the context is formal (such as in an invitation), spell out the state name.

Use the full nine-digit zip code whenever possible (check the Iowa State Postal and Parcel Web site or the current campus directory for a listing of extended zip codes for university buildings).

Abbreviate compass designations (N., S., E., W.), but spell out designations such as Street, Avenue, and Road.

For listing addresses in running text, use commas to separate elements, including U.S.A. (e.g., Direct inquiries to Office of Admissions, Iowa State University, 210 Alumni Hall, Ames, IA 50011, U.S.A.

Abbreviations/Acronyms

Abbreviations are read as a series of letters or made up of the first and last letters or shortened version of a word. Acronyms are read as a word, such as NATO or NAFTA. Avoid abbreviations in running text unless a very long name or term is repeated several times. Spell out at first occurrence with the abbreviation next to it in parentheses.

Exceptions to spelling out in text are those abbreviations and acronyms that are well known by the general public (e.g., CBS, HMO) or those used in technical publications where the abbreviations are common to a specific field and audience.

Acronyms of five or more letters often appear lowercase with frequent use, such as Nafta or Veishea.

A and an, use of

The use of a or an preceding an abbreviation or acronym is determined by the pronunciation of the first letter of the abbreviation or the pronunciation of the word formed by the acronym.

a NATO member, an ACT test

Academic degrees

In general, do not use abbreviations for degrees after a person's name unless it is necessary to establish credentials. Do not include the word degree after a degree abbreviation.

He has a B.A. in history.
not He has a B.A. degree in history.

Don't use Dr. with the degree designation. Use Dr. John Jones or John Jones, Ph.D.

Common practice is to use periods without spaces for abbreviations of degrees (B.A., M.S., Ph.D., M.Eng., M.B.A., LL.D. and LL.M.). The most recent edition of The Chicago Manual of Style, however, recommends omitting the periods unless required for consistency or tradition.

Degree abbreviations are best used in listings, while spelling the degrees out is more readable in regular text.

associate degree; baccalaureate degree, bachelor's degree and master's degree; doctoral degree, doctorate (don't follow doctorate with degree); bachelor of arts, master of science, doctor of philosophy.

Set off degree names by commas when they follow personal names.

Mary Jones, master of science in biology, is the coordinator of the program.

Addresses

Names of states and countries should be spelled out in text (especially if used alone); abbreviations may be used in lists, mailing addresses or where space is limited.

AL Ala. IL Ill. NC N.C. SC S.C.
AR Ark IN Ind. ND N.Dak. SD S.Dak.

FL Fla. MI Mich. OH Ohio WI Wisc.
GA Ga. MN Minn. OK Okla. WV W.Va.

If using the old abbreviations (such as Ala. and Wash.) within text, there should be commas before and after.

The three students from Omaha, Neb., roomed together.

Abbreviations such as Ave., St., Blvd., Hwy., N., E., S., NW, SW are used on envelopes and labels, but rarely in nontechnical text. Single-letter compass point abbreviations are followed by a period; two-letter ones appear without. Spell out compass points that are part of the street name.

4321 James Street SW

Ampersands

Company names, agencies, and organizations

Spell out company names in running text. Abbreviations such as Inc. and Ltd. can usually be omitted. Commas are not required around the abbreviations; but if used, commas must precede and follow the abbreviation.

The names of many agencies and organizations such as AMA and FCC are commonly abbreviated in running text after being spelled out on first reference. Use full capitals without periods.

Dates

Spell out names of days and months in running text. Do not abbreviate the words day, week, month and year.

Where space restrictions require abbreviations for days and months use the following:

  Jan.   Feb.   Mar.   Apr.   May   June   July   Aug.   Sept.   Oct.   Nov.   Dec.

In informal usages, the abbreviation of a year is often formed by replacing the first two digits with an apostrophe; decades by adding an s. Note that the apostrophe faces left, like a closing single quotation mark.

the class of '55
the 1960s and '70s

Designations of chronology such as AD and BC (full capitals, no periods) may be used in text and elsewhere. (Some prefer small caps with or without periods, which is acceptable as well.)

Etc., et al., i.e., e.g.

The abbreviation etc. stands for et cetera ("and other things"; not people). Do not use and etc. (et means "and"). Generally not used in formal text (phrases such as "and so forth" will do, it may be used in lists and within parentheses. Place a comma both before and after when used as the final item in a series and do not italicize.

The abbreviation et al. stands for et alii ("and others," meaning people, not things). Used most often in bibliographies. When it follows a single item, no comma is needed; when it follows two or more, use commas as you would in a series.

The abbreviation i.e. (id est) means "that is"; e.g. (exempli gratia) means "for example." Used most often in parentheses, place a comma after both.

Iowa State University/ISU

When writing about Iowa State, use Iowa State University first and follow with Iowa State. Avoid using ISU if at all possible, due to the potential confusion with Illinois State University, Idaho State University, and Indiana State University. Lowercase university when standing alone.

Iowa State University of Science and Technology is the official name of the university.
The university is organized into nine colleges.

Names and titles

Place a space between initials when listing names (John J. Jones, J. J. Jones; but FDR and LBJ without periods and spaces when abbreviating entire name).

Avoid dividing a name at the end of a line; however, if it can't be avoided, divide after the first name if only the first and last names are given, or after the initial(s).

Jr., Sr., I, and II. Use with full name only. Commas are no longer required around Jr. and Sr. (consistent with treatment of I and II). If commas are used, however, they should be placed before and after.

Civil or military titles. Abbreviate preceding a full name; with surname alone, spell out. (An exception is Senator; always spell out in formal text.)

Social titles. Ms., Mrs., Dr., and Mr. are always abbreviated when preceding a name; when used alone, spell out. Omit when an academic or professional designation follows the name.

Spell out titles used without names.

Plural forms

Form plurals of capital letter abbreviations by adding a small s (CDs ; DVDs).

Form plural versions of single word abbreviations by adding an s before the period (figs.).

Add an apostrophe and an s to abbreviations that are both capital and lowercase or that have two or more interior periods (Ph.D.'s).

Punctuation

Omit punctuation from abbreviations that are made up of initial letters. Periods are used with abbreviations that appear in lowercase.

NBA ABC e.g. loc. cit. f.o.b. fig.

The abbreviation etc. (et cetera) is preceded and followed by a comma, as is i.e. (id est, that is) and e.g. (exempli gratia, for example) when used within parentheses.

Omit space around ampersands when used within an abbreviation.

Texas A&M
R&D Magazine

When using the old state abbreviations in text (Ala., Calif., Nebr.) a comma should precede and follow the abbreviation.

The roommate from Los Angeles, Calif., will graduate in December.

Time

Use a.m. and p.m. (preferred) or set in small caps without periods. Don't use the abbreviations a.m. and p.m. with morning, afternoon, evening, night, or o'clock.

Use noon and midnight, not 12:00 a.m. and 12:00 p.m.

Place time zones in parentheses when needed. 2:30 a.m. (EST)

Technology and science

Abbreviations such as those used in the biological and physical sciences appear most frequently in tabular matter, notes, bibliographies, and references. Some easily recognizable ones such as CD or DVD may be used in nontechnical text as well.

Units of measure abbreviations are the same whether singular or plural; however, the plurals of time designations are often formed by adding an s.

100 lb. 2 gal. milk 8 in. 1 ft. (foot) 4 ft. (feet) 6 hrs. 25 yrs.

Names of chemical elements are normally lowercased when spelled out, but the abbreviations all have initial caps.

Co cobalt
