There&amp;#x27;s Category Theory for Computing Science by Barr and Wells (http://www.case.edu/artsci/math/wells/pub/ctcs.html), which is a good enough book but hardly comprehensive. I don&amp;#x27;t know any way round the fact that category theory is difficult to learn. I think that&amp;#x27;s partly inherent in the subject, not helped by the lack of a really good textbook suitable for beginners. (Here is the totality of my published work in category theory: http://arxiv.org/pdf/math/0604542v3)&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/math_0604542/"&gt;Paper and discussion history&lt;/a&gt;. A mention is not an endorsement.&lt;/p&gt;</description><category>math.CT</category></item></channel></rss>
