<h1>Papers about Cadabra</h1>

<p>
  The canonical introduction to Cadabra for high-energy physicists is
  the original paper (now updated for 2.x syntax),

<p>A technical explanation of the  motivation for writing this software,
  as well as a sketch of the internal structure, can be found in
  the paper</p>

<p>
  Please cite the three papers above when you use Cadabra in your own
  work; those citations are the only way to convince the bean counters
  that this software is useful!
</p>
<p>
  A lot of information on the internals of Cadabra and various parts
  written by Dominic Price has appeared in his thesis,

<p>
  A proper introduction to the new features of Cadabra 2 may appear at
  some point in the future.

<h1>Introductory papers to learn Cadabra</h1>
<a name="brewin"></a>

<p>Leo Brewin has written a very thorough new introduction to Cadabra for people
  who intend to use it in General Relativity, with loads of examples
  suitable for beginners,</p>
<blockquote class="reference">

<p>
Also from his hand is a nice paper on how to do Riemann normal
coordinate expansions with Cadabra, now updated to use Cadabra2 notation,
