Computer Modern and AMSFonts
in Type 1 (PostScript) Form
The PostScript Type 1 implementation of the Computer Modern
and AMSFonts produced by and previously distributed by Blue
Sky Research and Y&Y, Inc., are now freely available for
general use. This has been accomplished through the cooperation
of a consortium of scientific publishers with Blue Sky Research
and Y&Y. Members of this consortium include:
- Elsevier Science
- IBM Corporation
- Society for Industrial and Applied Mathematics (SIAM)
- Springer-Verlag
- American Mathematical Society (AMS)
In order to assure the authenticity of these fonts, copyright
will be held by the American Mathematical Society. This is
not meant to restrict in any way the legitimate use of the
fonts, such as (but not limited to) electronic distribution
of documents containing these fonts, inclusion of these fonts
into other public domain or commercial font collections or
computer applications, use of the outline data to create derivative
fonts or faces, etc. However, the AMS does require that the
AMS copyright notice be removed from any derivative versions
of the fonts which have been altered in any way. In addition,
to ensure the fidelity of TeX documents using Computer Modern
fonts, Professor Donald Knuth, creator of the Computer Modern
faces, has requested that any alterations which yield different
font metrics be given a different name.
The CM fonts collection includes the 75 fonts described in
Donald Knuth's ``Computer Modern Typefaces'' (Volume E of the Computers &
Typesetting series) as well as the ``line'', ``circle''
and symbol fonts associated with LaTeX.
The AMSFonts collection includes the Euler, ``extra symbol''
and cyrillic fonts.
The fonts are available in Macintosh and PFB (binary Type
1) outline formats. Users requiring the fonts in PFA (ASCII
Type 1) form should convert them with the aid of one of the
following tools, available from the Comprehensive TeX Archive
Network (CTAN):
fonts/utilities/ps2mf/pfb2pfafonts/utilities/ps2pk/ps2pk15/misc/pfb2pfasystems/msdos/4alltex/diskp1/pfb2pfa.zip
The fonts have exactly the same metrics as the bitmap versions
of the fonts generated by METAFONT. Therefore, the standard TFM
files (available from CTAN in fonts/cm/tfm and fonts/amsfonts/tfm )
should be used for TeX applications. However, note that the AMSFonts
do not come in all the sizes provided by the METAFONTed bitmap
versions.
Obtaining the CM and AMS Type 1 (PostScript) fonts
The canonical versions of these collections are located on the
AMS FTP server, ftp.ams.org , as follows:
Four system-specific packages are available for each collection:
- for use on Macintosh, containing the fonts in standard
Macintosh Type 1 format
- packaged as required for use by Textures
- packaged for use by OzTeX, CMacTeX, or other Mac TeX
implementations
- for use on a Windows or DOS system, containing fonts in
PFB format with PFM metrics files;
- for use on a Unix system, containing fonts in PFB format
with AFM metrics files.
The collections are mirrored onto CTAN at
fonts/cm/ps-type1/bluesky -- Computer Modernfonts/amsfonts/ps-type1 -- AMSFonts
Each system-specific package is accompanied by a READ.ME
file which contains instructions for downloading and installing
the fonts. Please review the appropriate READ.ME file in its
entirety before undertaking to install the fonts on your system.
The AMS does not provide installation assistance or
technical support beyond any installation instructions included
with the collection. Installation and use of these fonts
may require some technical expertise.
The file ``cmsample.tex '' which is included
with each CM distribution contains samples of all of the fonts
in the collection. Once you have installed the fonts, you may
typeset this file using Plain TeX to test your font installation.
No comparable test file exists for the AMSFonts collection.
History
The Type 1 versions of the Computer Modern fonts (1990) and AMSFonts
(1992) were produced by Blue Sky Research of Portland, Oregon,
and Y&Y, Inc., of Concord, Massachusetts, who published the
fonts in conjunction with their commercial implementations of
the TeX program.
Character outlines for the CM fonts were derived from high-resolution
METAFONT-generated character bitmaps by the ScanLab application
from Projective Solutions (Ian Morrison and Henry Pinkham),
applied and corrected by Douglas Henderson of Blue Sky Research.
The outlines for the AMS Euler fonts were derived algorithmically
from METAFONT code using tools developed by Y&Y. Character-
and font-level hints were programmed using software from Y&Y
(Berthold and Blenda Horn), with extensive hand work by Blenda
Horn. Font engineering, production, and packaging were by Douglas
Henderson and Berthold Horn.
The CMMI* fonts were revised in 1996 to conform
to Knuth's changes to the greek delta and arrow characters.
