"It has now been decided that the whole of the Diary shall be made public, with the exception of a few passages which cannot possibly be printed. It may be thought by some that these omissions are due to an unnecessary squeamishness, but it is not really so, and readers are therefore asked to have faith in the judgment of the editor. Where any passages have been omitted marks of omission are added, so that in all cases readers will know where anything has been left out."
When I read that I looked it up in Wikipedia [1] and it turns out that it's hilariously disingenuous and it absolutely was an "unnecessary squeamishness" (i.e. censorship of the "dirty" bits) that motivated the omissions.
I therefore picked up a cheap copy of the Latham & Matthews complete paperback edition and am rather slowly making my way through that. It's in eleven volumes - one for each year plus a supplementary overview. I'm still on 1662 but it's very entertaining in short doses. This edition, as well as including the bits that Wheatley sought to obscure, has rather nice illustration of London landmarks on the covers.
There are some other good bits in that Wikipedia page by the way - one of my favourites is the stuff about Lord Granville painstakingly deciphering a few pages of the "encoded" content while the instructions for decoding them were in the same library a few shelves away!
Some or all of this may be in the linked article, but alas it's paywalled (and archive.today didn't work) so my apologies if I'm just repeating its contents!
Pepys' writings nicely precede the stuff about Hooke [2], to whom someone linked yesterday, because Hooke collaborated closely with Christopher Wren (famously the architect of St Pauls Cathedral in London) in the rebuilding of many of the churches destroyed by the conflagarion of the city that Pepys observes and writes about in 1666.
