Q: I am used to writing “compared with” when discussing results/measurements. Can you please comment on whether this is correct?
A: This is addressed in the glossary in chapter 11. See “compare to, compare with.” You’ll see there that “compare with” is usually used when the aim is to examine similarities or differences in detail.
Q: I was trained in other settings to ignore having to write out the state on first mention if the city is well known, especially if the readership is primarily American. For example, Chicago, Los Angeles, and San Francisco would not require adding the state name on first mention. Something like Spring Green would. What would AMA style require?
A: Please see section 14.5, where this is addressed in detail. The key sentence is this: “At first mention, the name of a state, territory, possession, province, or country should be spelled out when it follows the name of a city.” In earlier editions, we used to follow a policy something like what you describe but changed that as it was a matter of opinion what was “well known” and what was not. Also, with the international readership of so many publications, this becomes a trickier question.—Cheryl Iverson, MA
