The Collation

Marginal calculations; or, how old is that book?

I’d like to make a pitch for recording a specific type of manuscript annotation in printed books and manuscripts: the “book age calculation.” These calculations turn up frequently on pastedowns and endleaves, and sometimes right in the middle of texts. They are usually in pencil, but sometimes appear in ink as well, as in this example from last week’s Crocodile.

Someone in 1872 calculates that this manuscript is 174 years old.

Wonderful to see this topic as it’s one I’m curious about (& charmed by), too. I’m a rare book cataloger and make a note in the holding record when I come across them. It would be great to have an official genre term for this as it does seem to be a common practice, at least in the English books I’ve seen. Searching our catalog just now–which would’ve been much easier with an approved term!–I found a copy of a 1579 book of English statutes with that date subtracted from 1623. For me, too, the 19th century is about as late as these seem to appear. “Date calculations” might be be a less clunky term but perhaps more cryptic? Thanks for bringing this up, Heather!

I’m so glad to hear that you are already noting this in your holdings records! Seems a good idea to use a consistent term internally until someone submits “book age calculation” as a provenance evidence term and it (hopefully) gets approved.

Oops! Sorry, that’s “1837” not 1873.

“Date calculation” or something like it might be better, since it’s not always about the age of the book. See http://mssprovenance.blogspot.com/2015/07/a-french-13th-century-psalter-at-smith.html where at the very end someone in 1873 is calculating the time that passed since a previous owner inscribed this 13th-century ms. in 1640.

Good point–a broader term such as “date calculation” could include not just the age of the book, but the duration between owners. Mary Person suggested “date calculations” as well, in her comment.

I’m cataloguing a 1695 edition of Camden’s Britannia (sadly lacking every one of the luscious county maps) and what do I find at the bottom of the title page? A neatly executed manuscript date calculation set out thus:

1849
1695 [printed]
154

It makes me wonder how many of these I’ve missed in the past because I didn’t know what I was looking at. Thanks again for the blog post.

That’s terrific! So your calculator wrote 1849 above the printed imprint, and the subtracted number underneath it? Why bother to write out 1695 if it is already there on the map! Thanks for sending this along, Christian.

If you start keeping some photographic records of these we might think about putting a group out on POP at some point. I’ll run the idea by the POP team of putting “date calculations” into our perspective provenance vocabulary too.
