History of science & #BookHistory friends: What was the size of the initial print run of Hooke's Micrographia? (I've frequently seen the 1st edition referred to as a bestseller, but haven't found a source that confirms how many copies the Royal Society commissioned...) #HistSTM #histsci 🗃️📜🔬

A belated Spencer Library #newacq thread here: a Book of Hours, Use of Sarum, created in circa 1430 (Pryce MS D1). A wonderful addition to our MSS holdings, and a good companion to the Vosper Hours. Let's start with the Crucifixion and the opening line of text: 📜 #libsky #rarebooks #booksky

Currently cataloging a French revolutionary pamphlet, dated "L'an deuxieme de la liberte" e.g. 1793 (best I can deduce). But then the imprint statement at the end gives the year 1790 COME ON THE FRENCH LETS GET IT TOGETHER.

LLM-generated bibliographies are a moral crime against bibliography. I think they should be banned by the relevant professional organizations.

You suddenly get a narrator describing your life and there’s no way to turn it off - everyone can hear it. While shopping, at work, at home, with friends - the voice narrating your every move goes on. Who do you hope is the voice of this narrator?

Before you get warm feelings about this story, keep in mind it was **labour and contract protections** that got these people back. Not some grand realization that Librarianship is necessary. Get unionized people. 1 / 2

For my collation folks: this MS has three signatures nested inside the first one. How do we feel about this as a formula (visually jarring, but it's an attempt): [1]⁴([2]²⁰+[3]¹⁴+[4]¹⁶) [5]⁴

A recent-ish acquisition here at Spencer from Bruce McKittrick in my cataloging cradle today: a 17thC Italian MS applying the rules of gematria to Italian, drawing upon the popular Renaissance conception of Kabbalah as “white magic”: 📜 #libsky #rarebooks #booksky
First page of a manuscript in Italian. Paper is browned, as is the ink. It’s in a cradle and the manuscript is from the 17th century.A page from the same manuscript (Italian, 17th century) but this page has a chart matching letters to numbers and a small manicule in the margin.Another page from the same manuscript (Italian, 17th century) with a number triangle and a chart of Hebrew characters
