This episode is a free sample of our subscriber only show, Locklisted, because the next episode of Backlisted has been delayed through illness (though given that its subject is the radio scripts of A Hitchhiker’s Guide to the Galaxy by Douglas Adams, this tardiness may not come as a complete surprise). A conversation about shelftalkers in bookshops leads to a broader discussion about where we get our book recommendations and Andy runs a quiz based on the principle of  algorithmic recommendation. There is also a discussion inspired by Thomas Bernhard’s pitch black 1980’s novel The Cheap Eaters (translated by Douglas Robertson) and John Boorman and Bill Stairs’ 1974 novelisation of the cult film, Zardoz. *Tickets are now on sale for our LIVE show in London on Wednesday May 14th where we will be discussing The Good Soldier by Ford Maddox Ford, with guest Alex Michaelides.  * To purchase any of the books mentioned in this episode please visit our bookshop at uk.bookshop.org/shop/backlisted where all profits help to sustain this podcast and UK independent bookshops. * For information about everything mentioned in this episode visit www.backlisted.fm *If you'd like to support the show and join in with the book chat, listen without adverts, receive the show early and with extra bonus fortnightly Locklisted episodes, become a Patreon at www.patreon.com/backlisted *You can sign up to our free monthly newsletter here  Learn more about your ad choices.
