In late April of 2019, Preservation Lab hosted an in-house workshop for lab staff with conservator and book historian Julia Miller.  The workshop curriculum consisted of Egyptian and Greco-Roman rolls and pocket rolls, a small model of the Kellis Agricultural Account Book (a wooden tablet model), and a model of the coptic codex Ms. 815, currently at the Chester Beatty in Dublin, which dates to approximately 5th/6th century (a multi-quire codex model).
