it have the laborsaving abilities of L
A
T
E
X for preparing indexes, bibliographies,
tables, or simple diagrams. These features are such a convenience for authors
that the use of L
A
T
E
X spread rapidly in the mid-1980s (a reasonably mature
version of L
A
T
E
X was available by the end of 1983), and the American Mathe-
matical Society began to be asked by its authors to accept electronic submissions
in L
A
T
E
X.
Thus, the A
M
S-L
A
T
E
X project came into being in 1987 and three years later
A
M
S-L
A
T
E
X version 1.0 was released. The conversion of A
M
S-T
E
X’s mathe-
matical capabilities to L
A
T
E
X, and the integration with the NFSS, were done by
Frank Mittelbach and Rainer Sch¨opf, working as consultants to the AMS, with
assistance from Michael Downes of the AMS technical support staff.
The most often used packages are amsmath (from A
M
S-L
A
T
E
X) and amssymb
(from the AMSFonts distribution). To invoke them in a document you write, e.g.,
\usepackage{amsmath} in the usual way. Installation and usage documentation
is included with the packages. For amssymb the principal piece of documentation
is the AMSFonts User’s Guide (amsfndoc.tex); for amsmath it is the A
M
S-
L
A
T
E
X User’s Guide (amsldoc.tex).

8.2 Fonts and Symbols in Formulae
8.2.1 Mathematical Symbols
Tables 8.2 on the next page to 8.11 on page 227 review the mathematical symbols(L 42–47)
available in standard L
A
T
E
X. You can put a slash through a L
A
T
E
Xsymbolby
preceding it with the \not command, for instance.(L 44)
u 6<vor a 6∈ A $u \not< v$ or $a \not\in \mathbf{A}$
Tables 8.12 on page 227 to 8.19 on page 229 show the extra math symbols of
the A
M
S-Fonts, which are automatically available when you specify the amssymb
package.

However, if you want to define only some of them (perhaps because
your T
E
X installation has insufficient memory to define all the symbol names),
you can use the amsfonts package and the \DeclareMathSymbol command, which
is explained in section 7.7.6.

The AMS distribution also contains a file diff12.tex which describes differences between
version 1.1 and 1.2 of A
M
S-L
A
T
E
X. Note in particular that in versions 1.0 and 1.1 of A
M
S-
L
A
T
E
X, which predated L
A
T
E
X2
ε
,theamsmath package was named “amstex” and included some
of the font-related features that are now separated in the amssymb and amsfonts packages.

Note that the Companion uses Lucida math fonts which contain the standard L
A
T
E
Xand
A
M
Ssymbols but with different shapes compared to the Computer Modern math fonts.
