Associate Professor Andrew Walkling recently reported on an ongoing project involving the collation of typographical variants in a late-seventeenth-century English book. His report, published in The Collation, the research blog of the Folger Shakespeare Library in Washington, DC, describes his work refurbishing and using the library’s Hinman Collator, a fascinating relic of mid-20th-century pre-digital technology. The project grew out of an issue first raised in his forthcoming book, English Dramatick Opera, 1661–1706, to be published by Routledge in 2019.
