Key Differences Between AACR2 and DCRM(B)

If you are used to cataloguing in AACR2, you will probably find it quite easy to make the transfer to Descriptive Cataloging of Rare Materials (Books), commonly known as DCRM(B). DCRM(B) is based on AACR2, but emphasises transcription where AACR2 allows interpretations, requires fuller description or transcription of certain elements, and provides more detailed guidelines for supplying copy-specific detail than AACR2. The attached table is intended as a basic overview for those whose experience is with machine-press books. It is therefore based on the main section of AACR2 and disregards AACR2's  section on 'Early Printed Monographs' (2.12-2.18F), which approximates more closely with DCRM(B).
