This weekend, June 6-8, the annual Red Square Book Fair is going to be held, albeit in more modest dimensions and with a lot of hurdles to keep people safe. Because quarantine is not officially over, it can be attended by book lovers and readers older than seven and younger than 65, who have registered ahead of time for one of the five daily 2-hour visits and gotten a QR pass. At the venue, which will be periodically disinfected, visitors must wear gloves and a mask, and stay at least 1.5 meters away from everyone.
Although about a dozen publishers backed out for safety reasons, more than 200 publishers will show and sell their books in seven spaces. There will be authors giving talks, although probably not signing books. There will be performances, particularly in honor of Alexander Pushkin, whose birthday is June 6. There will be actors reciting poetry and giving readings of prose. There will be bean bag chairs and special editions of newspapers.
You can see what you might be able to attend here, where there are also instructions on registration, getting a travel pass, and other rules of attendance.
