I’ve updated the Web links on my 2019 post Machen’s autobiography – all three volumes now online and I had also linked there to Strange Roads.
Two of the 2019 links went only to Hathi, which wasn’t ideal since they don’t let you download the entire book. Hathi can also be slow, and can stop working if it thinks you’re trying to ‘pirate’ the book by reading too many pages. The new links are to The London Adventure and Strange Roads, which are now free and openly public on Archive.org with downloads. This leaves only Things Near and Far as the lone Hathi-only title.
If you want them all in printed-paper as good texts and with the S.T. Joshi stamp-of-approval, there’s also the new book Autobiographical Writings by Arthur Machen which I’m told will ship in November 2020.
