   I noticed in the Reyes&Reyes blog the April 2, 2018 announcement:

   First Order Categorical Logic

   This document is a re-writing of the book of Makkai-Reyes with the same title. It is due to Francisco Marmolejo, who not only re-wrote it but made several corrections.

   Makkai-Reyes book

   This is the book

   • Michael Makkai and Gonzalo Reyes, First Order Categorical Logic: Model-theoretical methods in the theory of topoi and related categories, Lecture Notes in Math. 611, Springer-Verlag, 1977.

   Does this mean that it is copyright legal to link to the PDF they link above, or would it be better to link through their blog post.

   Currently there are ~10 nLab references to this book.

   Generic figures and their glueings

   Reyes&Reyes have also recently updated their 2004 blog post Generic figures and their glueings to give a link to the complete PDF of that book rather than just a sample, though the Wayback machine doesn’t say when that happened.

   • Marie La Palme Reyes, Gonzalo Reyes and Houman Zolfaghari, Generic figures and their glueings – A constructive approach to functor categories, Polimetrica Milano 2004.

   There are about 14 nLab references to that book that also need updating and being made consistent.

   I haven’t yet created REF Generic figures and their glueings because some may object to this approach or that it needs to be more elaborate or sophisticated.
