Q: Is it necessary to repeat the manufacturer name, city, and country after every repeated mention of a product, or is it sufficient to cite this information only after the first appearance?

A: Mention of the manufacturer’s name after the first mention should be sufficient. Also, please look at our (free) online Updates.

UPDATE:  Manufacturer information for Equipment, Devices, and Reagents:  In section 15.5 (page 583 in the print book), we will no longer require the inclusion of the location of the manufacturer. This is so easy to look up online, should anyone desire more specific details, that we believe it is not necessary to continue to require this. This change was made October 4, 2011.

You’ll see that we no longer require the manufacturer’s location to be included.—Cheryl Iverson, MA
