It's a blog! Mainly of book reviews.
Completely bizarre...so just like Roadside Picnic, then...except, no, bizarre in a totally different way...
I feel a bit dense because it took until near the end for me to figure out what the allegorical/satirical point behind it all was. Having done so, I'm surprised it got published at all in the USSR.
Also, does that darned integral equal zero or not?!
