This episode is a little different from a regular Backlisted, the next episode of which 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.
