In the Library, the two rangers accompanying you will read through the titles of several books, including one called Roadside Picnic (1977) by the Strugatsky brothers.

The book was the basis for Andrei Tarkovsky's 1979 film STALKER, which in turn was one inspiration for GSC World's 2007 videogame of a similar name: S.T.A.L.K.E.R. Shadow of Chernobyl.
