Describing the physical construction of manuscripts.
@collationBot is a Twitter bot created by Dot Porter that tweets collation formulas that are pulled from medieval manuscript descriptions hosted on OPenn, and from the British Library’s Hebrew Manuscripts.
A collation formula describes how a manuscript is constructed in terms of quires (that is, leaves gathered together) and leaves (single pieces of parchment or paper), and is usually in the format e.g., 1(8), 2-4(10) (that is, quire 1 has 8 leaves, quires 2-4 have 10 leaves each), although as the bot illustrates in actuality the formulas are many and varied!
