There's good news for those who were dismayed at the removal of the index in the latest update of the RDA Toolkit. It was announced today on the RDA Toolkit blog (http://www.rdatoolkit.org/blog/7768) that the RDA print index has been reinstated! As stated in the blog post:
"In the weeks that followed the April 14 release to RDA Toolkit, we heard from a number of users who were unhappy about the removal of the index from the Toolkit. In response to that feedback, we have added a PDF of the RDA Print index to the Tools tab of RDA Toolkit. This PDF file contains the index that will be part of the 2015 revision of RDA in print. The index has been revised and updated to reflect the changes to the RDA standard that were made since the April 2014 release and through the April 2015 release. The PDF is not hyperlinked, but it is downloadable and may be printed for personal use."
