Hein has announced the availability of the online portion of Melanie Lembke and Melissa Beck's revised fourth edition of Cataloging legal literature. The text has been upgraded from an image based pdf version into an interactive, searchable resource. The title is designed to be used in conjunction with the RDA Toolkit, and feature links from the text directly to relevant instructions in the toolkit.
If your library has a standing order for the AALL publications series, you will be authenticated into the HeinOnline database version of the title.
