<h1>Proprietary fonts and/or their free equivalents</h1> <p>arXiv's TeX installation does not have any proprietary fonts. Only fonts which are available at no charge and with non-restrictive licenses can be used within arXiv's TeX system.</p> <p>There are partial solutions for some popular fonts, in particular some from Adobe, either via use of free subsets thereof, via substitutions, or via a combination of both. This applies in particular to Minion Pro, Myriad Pro, Utopia, Garamond, and possibly others</p> <h2>MinonPro Fonts</h2> <p> Update: Due to lack of demand in the past 3 years we do no longer support MinionPro. arxiv switched to a <strong>texlive 2009</strong> based system on 12/31/2009 and MinionPro is not part of texlive. </p> <p>Old News: arXiv does support the base set of MinionPro fonts, i.e. the <strong>Regular</strong>, <strong>Italic</strong>, <strong>Bold</strong>, and <strong>BoldItalic</strong> shapes, however the "semi", "mid", or "optical" shapes are not available. Thus in particular the class option <code>[opticals]</code> is not supported at arXiv.</p> <p>See <a href="http://www.ctan.org/tex-archive/fonts/minionpro/">http://www.ctan.org/tex-archive/fonts/minionpro/</a> for more details.</p>
