Sometimes bibliography looks like this, and by extension, rare book cataloging. 4 OCLC records, 3 secondary sources, flashlight for watermarks, etc: all to determine that our copy of “Cryes of London” is from 1689, from the fifth edition, first impression: 📜 #bookhistory #booksky #libsky #rarebooks

Toured our offsite high density annex for @kulibraries.bsky.social today: WILD. Was not ready for the sheer scale of the place, but loved how cold they keep it! 2.3 (ish) million items… and growing every day.

Also got to see their Sidereus. A really nice lightly trimmed copy, worth the moon etchings supplied by hand on pasted in paper! Long term work on the revision of Paul Needham’s excellent census with Nick Wilding…

And here is the Royal Danish Library’s copy of the 1725 Historia Coelestis. Hoping Rev Flamsteed looks kindly on our work. This copy turned up some interesting material, including the binding with the cipher of Christian the 7th!
