Considering it's not a mighty tome, there seems to have been an inordinate number of bugs and problems resulting in the tardy appearance of the 2nd Edition of The Roof-Climber's Guide to Trinity. But then, it's been gone 79 years so an extra month is probably no great shakes. And then, it arrived the day before Oleander moved to a land sans internet for two weeks so I'm only able to tell you of it now.
Including and supplementing the information from two chapters in the previous guide, the 1930 second edition is otherwise completely rewritten and incorporates new routes, quotes, illustrations and a new format.
Although barely granted publication permission by Geoffrey Winthrop-Young, the authors of the 2nd edtion rightly noted that 'The conquest of the Great Gate in November 1927 marked a new epoch;' and that 'so many fresh climbs have been discovered in the subsequent three years, that a fuller edition of the old guide was felt to be desirable'.
