In the late 1990s, a collection of fiction by notable Russian scifi writers, titled "The Time of the Apprentices", was published in Russia (with an endorsement of Boris Strugatsky). The pieces in the collection build upon Strugatskys' ideas and works, and many of them are set in the Noon Universe. The same period saw the re-release of all Noon Universe novels as part of the "Worlds of Strugatsky Brothers" series. This re-release is notable for introductory articles written by literary critics from the perspective of Noon Universe historians looking back on the events of the said novels several decades later.
