On 30 November, the PCLA sent out a bundle of documents – all in Latin of course – relating to the work of the Commission and the Subcommission in which Cardijn was involved.
It also included the reference codes that were to be used for the various kinds of documents that were being produced:
CV = Various kinds of circular letters
Pr = Proposals for Council documents
Ri = studies and research
Corr = Correspondence of our Commission
Ra = Session reports.
