The American Mathematical Society provides custom / document classes for AMS journals and book series. These may obtained by anonymous FTP from the e-MATH system e-math.ams.org, directory, in the author-info area. (Note that directory structures may occasionally change; if you have trouble locating files you need, please contact AMS Technical Support; see Appendix E.) Specific and generic classes can be requested by e-mail to ams-latex@math.ams.org or ordered on floppy disk through the AMS Customer Services Department at cust-serv@math.ams.org or 800-321-4267.
