		     Check List for Electronic Manuscripts

			Fields Institute Communications


- The author should be familiar with the "Guidelines for Preparing Electronic
  Manuscripts" for AMS-LaTeX manual.

- The author should proofread the paper before submitting to the AMS.

- In article titles, capitalize the first and last words and all nouns,
  pronouns, adjectives, adverbs, and verbs; lowercase articles, conjunctions,
  and prepositions unless they are first or last word.

- The running heads for the left-hand (even-numbered pages) should have the
  author(s) name(s) all in initial caps and lowercase.  Names in running heads 
  should match names as given on the first page (shorten to fit only if 
  necessary).

- The running heads for the right-hand (odd-numbered pages) should have
  the title (shortened if necessary) all in initial caps and lowercase.

- The subject classification numbers should be listed as the first unmarked
  footnote on the first page.

- Grant information should be listed as unmarked footnotes on the first page.

- Citations in the manuscript should be coded using "\cite".

- References should include all available information.

- The address, current address (if different) and e-mail address of each author
  should be included.

- The .TEX files should include NO "input" files.

- All definitions should be at the top of the file and none of them should
  redefine any LaTeX or plain TeX commands.

- Definitions should be used consistently throughout the paper. Do not include
  macro definition files in which all of the definitions are not used.  All
  definitions appearing in the file must be used in the file.

- No definitions should be used for formatting text; only the LaTeX 
  environments should be used.

- All author-prepared submissions require that a .DVI file be submitted along
  with all related .TEX and encapsulated PostScript files (please refer to
  Graphics section below for guidelines for submitting files with graphics). 

- The author should enter whatever breaks are necessary in order to make
  certain that
	- facing pages align at the bottom.  Page spreads may run one line long
 	  or one line short.

	- no characters run out into the margins.

	- Figures and tables must appear at the top or bottom of a page. 
	  Figures and tables are placed as close as possible to their text 
	  reference - preferably: (1) on the same page, or (2) on the facing 
	  page.  They must appear before a new first level heading occurs, and 
	  never before the  first level heading for the section in which their 
	  reference occurs.  

GRAPHICS
--------
  Figures which were created electronically can either be imbedded within the
  .TEX file (if they are encapsulated PostScript graphics) or they can be
  submitted as separate files.  A printed copy of the figures must be supplied
  in either case.

  For figures which were drawn, the author must submit paper copy of the
  graphics, of as high quality resolution as possible.

  If the graphics are not imbedded within the .TEX file, the author should allot
  the correct amount of space to be left for each figure right in the .TEX file
  using figure macros.

  Electronic graphics which are not submitted as encapsulated PostScript files
  should be submitted on Macintosh diskettes as Adobe Illustrator, MacDraw or
  MacPaint files. If a graphic is done in any format other than those mentioned
  above, then the electronic file will probably not be useful to us at all, but
  you may wish to check with us. No matter what method was used to produce a
  graphic, we repeat that it is necessary to provide a paper copy and NOT to use
  \special commands (or macros which use \special commands) to include the
  graphic in the TeX file.

  There are two ways to include PostScript graphics in your file which will be
  acceptable for publication at the AMS. The first is to send us the PostScript
  output of your dvi-to-PostScript driver. However, please contact us first for
  further guidelines for this case before you send any files. Alternatively,
  you may include the PostScript code for Encapsulated PostScript files. These
  may be included in the TeX file with \special commands, but ONLY if it is done
  with either the public-domain file epsf.tex (or epsf.sty) developed by Radical
  Eye Software, or the public-domain file psfig.tex, version 1.9 or later. As a
  rule, the AMS does not provide these macro files to authors, as they are 
  widely available in the TeX community. Also, there are a few requirements if 
  these macros are used:

   (a) Please DO NOT include any path names of the included PostScript files. 
       For instance, do not say \psfig{file=/usr/joe/book/figures/fig1.ps}.
       You must remove all explicit path references, so that the above would
       become \psfig{file=fig1.ps}. 

   (b) Please include printed copies of all of the PostScript files for the
       figures with the TeX file.

   (c) When you send the .dvi file, and you used psfig.tex, you must have used
       the version which is compatible with dvips, rather than any other
       version of that file. You will know this version because it includes
       another file called epsf.tex, and gives credit to Tom Rokicki for the
       macros for reading in the PostScript file.
