| Oct 4, 2022 at 23:45 | comment | added | varkor | @Emily: sadly John Gray died in 2017, so it is no longer possible to ask him about this work directly. (I don't know why his website hasn't been updated accordingly.) | |

| Oct 4, 2022 at 22:52 | comment | added | Emily | @varkor I tried emailing Gray asking about his notes around the middle of 2020, but I got a notification from the "UIUC mailer daemon" saying that the email failed to be delivered after 5 days and that Gray's email is "over quota". I'm not sure if this would still happen again today, but maybe it would be a good idea to write a letter (or send a fax!) to him instead. | |

| Oct 4, 2022 at 13:01 | comment | added | varkor | I would like to second the question by @DavidRoberts (hopefully generating another notification). | |

I mainly want to bump the question, since it's still 1) interesting 2) has no answer and 3) has a chance of having an answer now after almost a decade since it was first asked (P.S. I followed Trimble's suggestion to just email Gray, but there are was a server error and the email didn't reach Gray)

| Dec 24, 2010 at 11:20 | comment | added | David Roberts♦ | For everyone else: reference [168] from Johnstone is "Formal category theory II, To appear". @Buschi My advice is to look at work by Street, Kelly and Lack. I don't have proper references at the moment, I'm afraid. 'Tis late and I've got to get up early for prezzies :) At least look at Fibrations in bicategories by Street: archive.numdam.org/article/CTGDC_1980__21_2_111_0.pdf | |
