The Art of LaTeX: Common mistakes and advice for typesetting proofs
Most of this is good advice, but I don&#x27;t see the \mathbbm vs. \mathbb distinction as anything other than subjective taste.<p>Also, I use things like<p><pre><code>  \newcommand{\abs}[1]{\left| #1 \right|}
</code></pre>
in the preamble. This way, I can use \abs{...} without any asterisks, and it automatically adjusts its size. In the 1% situations where I don&#x27;t want it to adjust the size, I write the delimiters manually.<p>Making maths look good in LaTeX is pretty well-understood these days; authors who don&#x27;t are usually just being lazy. The big undocumented mess with LaTeX is making bibliographies work correctly. The &quot;standard&quot; bibtex workflow is broken in many ways, and I have never seen a tutorial on how to fix it. With bibliographies being such a minuscule part of a mathematical paper, I&#x27;m not surprised that no one cares, but the result is lots of references that are imprecise, missing important info or plain wrong.
