 This package, based on txfonts, provides many fixes and enhancements to the txfonts package, splitting it into two separate packages---newtxtext and newtxmath, which may be run independently of one another. It provides scaling, improved metrics, and other options. In particular, newtxmath offers a libertine option which substitutes Linux Libertine (provided with TeXLive and MikTeX) italic and Greek letters for the default Times letters, providing a good match for the Libertine text font, which is heavier than Computer Modern but lighter than Times, and in my experience, looks very sharp and clear on the screen.

 \textbf{Caution:} In encodings {\tt T1} and {\tt LY1}, the macro \verb|\mathrm| does not produce what you might expect for Greek letters, due to the difference between those encodings and {\tt OT1}. But what were you expecting with \verb|\mathrm{Gamma}| anyway? In {\tt T1} and {\tt LY1}, you'll get a math accent.
+\section{Alternate forms of glyphs}
+Several math glyphs have alternate forms:
+\begin{center}
+  \begin{tabular}{@{} llll @{}}
+    \hline
+    Command & Result &  Alternate Commands & Alternate Forms\\ 
+    \hline

+You should be aware that using \verb|\varnothing| requires loading AMSb.\\
+To use an alternate form throughout your document without changing all occurrencesvof the usual command, insert something like the following in your preamble after loading \texttt{newtxmath}:

 This option allows the use of MinionPro as math letters (Latin and Greek) within  the math font, but there are some caveats:
