Move the mouse or scroll your iPad screen to the space at the close of Amazon.com “Editorial Reviews” section for Daniel Levin Becker’s excellent Many Subtle Channels: In Praise of Potential Literature (Harvard UP 2012).
There, you’ll find a repetition of the “Book Description,” from earlier in the page, now inflected with all-too-common Amazon character errors:
The youngest member of the Paris-based experimental collective Oulipo, Levin Becker tells the story of one of literature’s quirkiest movements—and the personal quest that led him to seek out like-minded writers, artists, and scientists who are obsessed with language and games, and who embrace formal constraints to achieve literature’s potential.
“’s” is html code for a right singly quote, and “&mdash,” of course, is the em dash (—). These reverse-engineered impregnations of the Descrption are certainly errors, but also candy-store windows for those who take a sly delight in the structural underpinning of how words on a web page may be “put” there, so to speak, in the first place.
