The Instrumenta series aims at collecting reference
works (concordances, preliminary studies, preparatory editions,
studies on manuscript tradition, repertories of apocryphal texts,
bibliographies) in attached volumes of the Corpus
Christianorum, Series Apocryphorum. It will meet the same
scholarly requirements as does the Series Apocryphorum.
The series is directed by the 'Association pour l'étude de
la littérature apocryphe chrétienne' (AELAC).
