Chapter 2, section 1, level 4*: FW: 30-34.29

Proofs (missing) for Contact Collection. See JJA 45: 1.

Revisions on the missing Contact Collection proofs are inferred from the Contact Collection pages included for convenience in the Archive as level 5' (q.v.), and are noted in the genetic representations as “IM”. Note that some of the differences between level 3 and level 5' may have been uncorrected typographical errors rather than intentional revisions.
