       Four Font Sets in Type 1 format now available for NeXT:
*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***

There has been some discussion recently regarding font sets in Type 1
format for use on NeXT computers, particularly with respect to fonts
containing mathematical symbols, operators, relations, and delimiters.
Here is some information on Type 1 font sets supplied by Y&Y in a form
suitable for easy installation on the NeXT.

List of Font Sets: 
-----------------

(1) Lucida (R) Bright + Lucida New Math - 25 fonts, over 5000 glyphs

    4 serif fonts, 4 san serif fonts, 4 fax fonts
    4 typewriter (fixed width), 4 math fonts
    Blackletter (Fraktur), Calligraphic, Handwriting, Slanted etc

(2) BSR Computer Modern fonts	 - 75 fonts, over 9000 glyphs

    The complete set of CM fonts - all standard design sizes.
    Also, each text font has 58 accented characters added (unencoded).

(3) AMS Font Set		 - 35 fonts, over 2700 glyphs

    6 Euler fonts (three design sizes each), 3 math fonts
    (includes `blackboard bold' a.k.a. `open-face' characters),
    5 Cyrillic fonts, math bold italic, math bold symbol, etc

(4) LaTeX + SliTeX font set	 - 21 fonts, over 600 glyphs

    LaTeX line, circle, symbol (different design sizes, weights),
    3 sans serif `lcm', and 5 `logo' fonts. Mostly useful for
    LaTeX picture environment, and for making transparencies.
    (LaTeX primarily depends on CM fonts, the above are `add-ons').

Advantages of fonts in Type 1 format: 
-------------------------------------

(*) Using fonts in Type 1 format makes it possible to produce truly
    resolution-independent PostScript output that will run on
    laser printers for proofing and on image setters for type setting.

(*) Fonts in Type 1 form provide for preview at arbitrary
    magnification without visually distracting resampling artifacts of
    bitmap fonts.

(*) Type 1 fonts take up less disk space than hi res bitmap fonts.
    This is particularly important if you would need both 300 dpi and
    400 dpi bitmaps.  (This is less of an issue if you are only
    generating the bitmap fonts on demand as you need them).

(*) Display PostScript loves Type 1 fonts!

(*) Fonts in Type 1 form make it possible to easily paste typeset
    material from one application into another.  For example, use TeX 
    to typeset some equation, create an EPS file, import that EPS file

    into a drawing program to scale, position and crop where you want 
    it to appear in a figure.  Conversely, import figures with 
    nomenclature in the same font as that used for text in TeX.

(*) The TeX -> EPS -> graphics program process is actively supported
    as a "Service" (i.e. a menu driven way for one NeXT application to
    `message' another) in NeXT-TeX 3.0.  You can write some TeX,
    scroll it with the mouse, and hit a key command or a menu and an
    EPS graphic appears which can be dragged and drop it into any
    application that will accept it. 

(*) With the new NeXT-TeX it's easy to also switch back to using the old
    bitmapped PK fonts, should there be a need to do this.   


Font Set Format: 
---------------

All font sets from Y&Y are in fully hinted Adobe Type 1 format (ATM
compatible).  Such fonts are also referred to as `PostScript Fonts' in
the TeX world, and `ATM fonts' by Mac and MS Windows users.

The font sets for the NeXT come in PFA (`Printer Font ASCII') format
with complete AFM (`Adobe Font Metric') files.  PFA format is what the
Display PostScript system is expecting.  (Font sets for IBM PC
compatibles, on the other hand, are normally supplied in PFB -
`Printer Font Binary' - format.  Fonts in PFB format would have to be
converted to PFA format before being used on the NeXT).  Display
PostScript on the NeXT is rather fussy about details of the AFM file
format and contents.  The AFM files from Y&Y are tuned for this (On
other platforms, AFM files are not as important, and so often have
features or lack entries that make them unacceptable to Display
PostScript).

The font sets come with detailed installation instructions as well as
a shell script that automates most of the installation process.  The
font sets are on DOS diskettes but without annoying extra control
characters (like the control-M used to terminate lines in DOS).

Use with NeXT programs: 
----------------------

The fonts appear in the font panel once installed and can be used with
any program on the NeXT.

Some additional material is provided for use of the fonts with TeX,
such as TFM (`TeX Font Metric') files, as well as files containing
additions that can be made to `psfonts.map' for use of the fonts with
DVIPS.

The CM, AMS, and LaTeX + SliTeX font sets are the Adobe Type 1
versions of these well-known font sets used widely in TeX.  Note that
these fonts, in their native form, have some features (such as lacking
a `space' character, for example) that make them awkward to use with
programs other than TeX.  Shell scripts are provided to rectify this.

Lucida Bright + Lucida New Math:
-------------------------------

The Lucida Bright fonts are the basis of the `new look' design of
`Scientific American'. These fonts have also been used in several
technical books (such as the RIDT 91 Proceedings). Lucida New Math
completes the font set with over 700 math symbols, operators,
relations, delimiters.

These fonts can be used with any program, but there are also TFM
metric files specifically for working with TeX.  In addition, TeX
macro/style files are provided to completely replace Computer Modern
fonts in both plain TeX and LaTeX, if so desired.  Just `\input
lcdplain' or `\input lcdlatex' at the head of the TeX source file.
(And `\input stanacce.tex' to override hard-wired CM-specific accent
positions in plain TeX and LaTeX).

(*) A single line switches a TeX job totally from CM to LB + LNM!

    (And commenting out that line switches back to CM.

Three of the Lucida New Math fonts are laid out the same way as cmmi*,
cmsy*, and cmex* `below the waist' (that is, char codes 0 - 127), but
each have an additional 100 or so characters above.  The fourth math
font contains yet more operators, negated relations, arrows and such.
Together the four math fonts cover the CM math fonts, the LaTeX symbol
font and the AMS math fonts.  In fact, the file `amssymlb.tex' defines
AMSTeX macro names for accessing some of these characters, such as the
`blackboard bold' characters (Note that you do not need to actually
run AMSTeX to gain access to these characters).

Files are also included to support the NFSS (New Font Selection
Scheme).

Lucida Bright + Lucida New Math is presently one of a VERY small
number of alternatives to Computer Modern that comes complete with
math fonts.  (One reason there are so few is that a `math font' for
TeX is much more than just a collection of glyphs). And LB + LNM is
the ONLY alternative consisting entirely of fonts in Type 1 format.

Some other items of note:

(*)	There are significant educational discounts on the font sets.

(*)	The font sets from Y&Y install `seamlessly' on the NeXT.

(*)	Y&Y also carries advanced software for `bitmap-free TeX' on
        IBM PC.

(*)	The font sets are available for other platforms as well.
