Dates
Dates may be formatted differently depending on where they are used. In all cases, years should be expressed with 4 digits unless part of a proper title.
Narrative/Note Text Formatting
Dates in narrative text follow a month, day, then year format. When citing year ranges, do not use dashes and include all digits. Examples follow:
- October 12 (not October 12th)
- October 12, 1952 (when used in narrative the year should be followed by a comma)
- September 1990 (no comma)
- 1980s (no apostrophe)
- 1872 to 1888 (not 1872 to 88)
- from 1940 to 1960
- between 1980 and 1990
- The 21st century; 21st-century technology
Component List Formatting
In normalized fields, all dates should be entered in the ISO 8601 Standard, as follows:
- general-to-specific approach — the year first, followed by month, then day
- each element is separated by a hyphen ("-")
- Numbers less than 10 are preceded by a leading zero
- YYYY or YYYY-MM or YYYY-MM-DD
If date is approximate, or includes months and days, a date expression should also be entered. Dates are still formatted as year - month - day, however the month should be written out. Do not repeat years or months in expressions of date ranges. Semesters may also be referenced in the date expression.
- 2014 July 12-14
- 2007 August 12 - October 31
- 2009 April 5 - 2010 May 1
- 2015 Fall
Note any significant gaps in date ranges.
- 1903, 1950-1955
For approximate dates, add qualifiers.
- circa 1952-1978
- circa 1975 August
- 1892 or 1893
- before 1920
- after 1920
If a date is not able to be determined, use "undated."
Numbers
Use a comma in numbers of four digits or more: 2,670.
Spell out numbers that begin sentences.
Spell out numbers from one to nine. For all other numbers, use digits.
Capitalization
(These are Chicago Style Manual rules, used by Tech Talk and MIT Press)
- Ad hoc, de facto, e.g., i.e.
- In narrative text: use lowercase for words such as president, chancellor, unless being used as a title (exceptions are the Corporation, which is referring to the MIT Corporation, the Association when referring to the Association of MIT Alumni and Alumnae, and the Institute) otherwise: Professor Vest, President Vest, the president; the provost; the dean; Department of Chemistry, the department of chemistry; Center for International Studies, the center.
- Series and subseries titles: capitalize each word
- Folder title: capitalize only the first word of the folder unless it is the official name of a body or entity, or the title of a book or journal article.
- If it IS the name of a body or entity, or a book or journal title: capitalize the first letter of all words except a, an, the, and prepositions as well as the first letter of the title and subtitle no matter what the word is.
- In notes where referring to boxes – do not capitalize Box
Abbreviations
- Omit periods in abbreviations of academic degrees: BS, MS, PhD, ScD (use bachelor's degree, master's degree, doctoral degree or doctorate to spell out degree)
- Omit periods in country and state abbreviations: US, UK, UN, MA, MA
- Omit periods in MIT and in all acronyms of three or more letters, use MIT as an abbreviation in bibliographies and footnotes, but not in collection level title with rare exceptions (MIT Libraries, MIT Press).
- Spell out Massachusetts Institute of Technology in citation of collection.
- In narrative fields: Use acronym after the first appearance of the full name, spell out full name then put acronym in parentheses after it
- At series/folder/item level: If known, spell out full name and then put the acronym in parentheses
- Names: Spell out names when known, unless persons are known by their initials
- Example: Greta Suiter instead of G. Suiter
- Example: J.K. Rowling
