I thank the many contributors to the $n$Lab for creating an invaluable online resource for aspiring and professional category theorists. (Knowledge Representation in Bicategories of Relations, Evan Patterson)

The author would like to thank Urs Schreiber for sparking his interest in the topic through many enthusiastic posts on the nLab and nForum. Syntax and semantics of linear dependent types M Vákár - arXiv preprint arXiv:1405.0033, 2014

Hamiltonian anomalies from extended field theories S Monnier - Communications in Mathematical Physics, 2015 - Springer … 5 Dai-Freed theories. An appendix contains reviews of several concepts used in the main text. The nLab (http://www.ncatlab.org) is a very useful reference for many of the higher categorical concepts appearing in the present paper.

[PDF] Motivic Homotopy Theory B Gheorghe - 2012 - math.wayne.edu … For each section, we list the important definitions and results, and give the reference it is taken from. When no reference is given, it usually means that this is taken from the internet, mostly ncatlab.org.

Deformation theory from the point of view of fibered categories M Talpo, A Vistoli - arXiv preprint arXiv:1006.0497, 2010 - arxiv.org … For many more, here are two good online resources: Charles Doran’s historical bibliography (http: //www.math.columbia.edu/~doran/Hist Ann Bib.pdf) and the nLab page on deformation theory (http://ncatlab.org/nlab/show/deformation+theory)

Since there is little use in my referring the reader to a reference work that I am barely acquainted with, I shall refer instead to my favorite one, which is the nLab [nLab]. The nLab contains basic information about many concepts, and when the information one finds there is insufficient or incomprehensible, then there are often valuable references to other works.

Cependant, le but de cette approche sera d’aller plus loin et de parler de categories superieures: ces bêtes sont devenues populaires en physique theorique, grâce aux blogs et articles de John Baez, http://math.ucr.edu/home/baez/week73.html, et d’une activite assez importante autour du n-lab, http://ncatlab.org/nlab/show/HomePage. http://www.iecl.univ-lorraine.fr/~Wolfgang.Bertram/WB-coursED.pdf

People who wish to learn more about category theory can use the references in the text, consult modern introductory texts like [4, 65], or use online resources such as ncatlab.org or Wikipedia Bart Jacobs, http://www.cs.ru.nl/B.Jacobs/PAPERS/ProbabilisticReasoning.pdf

Urs Schreiber, for patiently listening to me, and for creating and maintaining a resource as useful as the nLab, Alberto Garcia-Raboso, https://arxiv.org/abs/1501.05872

D.P.’s gratitude extends to the nLab for being a wonderful resource. https://arxiv.org/abs/1912.10544
