In notes and source citations. Some Latin abbreviations required in notes and in source citations are not appropriate in the body of a paper.
| cf. | compare (confer) |
| e.g. | for example (exempli gratia) |
| et al. | and others (et alia) |
| etc. | and so forth (et cetera) |
| i.e. | that is (id est) |
| N.B. | note well (nota bene) |
In addition, except in notes and source citations, do not abbreviate such terms as chapter, page, and volume or the names of months, states, cities, or countries. Two exceptions are Washington, D.C., and U.S. The latter abbreviation is acceptable as an adjective but not as a noun: U.S. borders but in the United States.
