A platen is a diary. Under the microscope, forty years of strikes map the writer's habits better than the writing does.
Every note in this journal was typed at the bench after closing, on whatever machine was struck up that day. The one that wrote this entry is noted in the repair ledger, because everything here is noted somewhere.
The works keep their own hours. Ink mixed on Tuesdays, bench photographs taken on Thursdays, the ledger written every day without fail since 2004. What we have learned is written down twice: once for the record, once for you.
If a line here rings a bell, the bell is real. Come in on a Saturday and count the rings yourself.
