Paper redaction

Rarely redactions are made by actually cutting out the offending content. (Usually they cross out or cover the content and then photocopy it.) This is from an AEC General Advisory meeting in the late 1940s, and the removed content refers to production data on "urchin" neutron initiators from the Dayton plant.
