 The goal of this package is to provide remedies for the above, where  possible. This means, in effect, providing virtual fonts with my personal effort at correcting the metric issues, rewriting the font-loading macros usually found in a \textsf{.sty} and/or \textsf{.fd} files to admit a scale factor in all cases, and providing a \textsf{.sty} file which is extensible and from which any such math alphabet may be specified using a standard recipe.

+\item The {\tt pxtx} package consists of virtual fonts drawn from the math alphabets in the {\tt pxfonts} and {\tt txfonts} packages, with modified metrics. The calligraphic fonts are identical to those in the Mathematica package, but the others seem distinct. The {\tt pxtx} package is part of \TeX\ Live.
 \item The ESSTIX collection is a creation of Elsevier Publishing in 2000, though never officially released by them. Before development was complete, the collection was donated to the STIX math font project, to which it seems to have been a precursor. Distribution has since been deprecated, but in my opinion, math alphabet fonts, especially math script fonts,  are so rare that none should be allowed to become extinct. The BlackBoard Bold ESSTIX font (\textsf{ESSTIX14}) is  close to both the mathpi and Fourier Blackboard Bold fonts, and the fraktur ESSTIX font (\textsf{ESSTIX15}) is  similar to mathpi fraktur. However, the ESSTIX script font (\textsf{ESSTIX13}) seems to be a distinct and interesting face. The PostScript versions of these fonts have been  hard to find, but the TrueType versions may be found embedded within the \textsf{Amaya} project, available at\\

 The Mathematica fonts are not of very high quality as a collection, but they have some good parts. In particular, the calligraphic math font may be turned into a useful target for \verb|\mathcal| after its metrics have been fine-tuned.
  You are missing out on some good stuff if you don't install this free collection.
+\item The {\tt txfonts} and {\tt pxfonts} packages provide a number of math alphabets that deserve more attention---the fraktur in particular is quite handsome but should perhaps be scaled up a bit.
 \item
 The \textsf{rsfs} package is not suitable for \verb|\mathcal|, being much too slanted. The best options for \verb|\mathcal| are \textsf{rsfso}, \textsf{esstix}, \textsf{boondoxo} and \textsf{mt}, the latter requiring the (non-free) \textsf{mtpro2} collection.

 Lucida fonts generally need to be reduced in scale to match other math and text fonts.
 \item Zapf Chancery need to be scaled up by 15\% or so. This font is not really suited for use as a math alphabet due to the disparate heights and depths and the long tails on some glyphs. Use with care.
 \item Mathematica fraktur is quite readable, but not very attractive, seeming to have random variations in baseline and height. It's also a bit too heavy to be a good match to most other fonts. Similar comments could apply to Lucida fraktur, which has a very distinctive appearance with some features more similar to \textsf{Duc de Berry} than to other fraktur fonts.
-\item The calligraphic fonts break down into four natural groups---(i) the upright styled Euler and Curly; (ii) the less-embellished CM, Lucida, Zapf Chancery, ESSTIX, dutchcal and Mathematica; (iii) the moderately sloped but more embellished Mathpi, Mathtime, rsfso and boondoxo; (iv) the heavily sloped rsfs and the slightly less sloped boondox. My preference, if not using \textsf{mathtime} or \textsf{lucida}, is to set \verb|\mathcal| to one from group (ii) and \verb|\mathscr| to one from group (iii).
-\item Blackboard bold can look poor in some cases. In my opinion, AMS bb and some of the others show up as ghostly (gray and indistinct) especially on the screen and may not appear to match the weights of other math glyphs. (Both AMS bb and Mathtime Pro 2 Holey Roman appear to be formed by removing the interiors of solid glyphs from a bold, seriffed font. Mathtime Pro 2 Holey Roman Bold is a much better fit to most math fonts of weight heavier than Computer Modern.) Fourier,  Mathpi, ESSTIX and boondox bb appear to be very close in style, with mathpi bb a bit less sharp. Mathpazo bb and Mathematica bb have a heavier appearance and should work better with fonts other than Computer Modern.
