Crosswalks. The General Notices page also provides a crosswalk document that shows current USP, NF, and FCC text side-by-side with the proposed revised text for easy comparison. The proposed revisions as they compare to the General Notices in USP 30, NF 25, and FCC 5th Edition are presented at USP's website.

Revision process. After the close of the initial comment period on Aug. 31, 2007, USP staff will review carefully all comments received and incorporate revisions as appropriate. Throughout the summer of 2007, USP Expert Committees also will review the draft, comment on proposals, and consider related changes that may be necessary, including changes to General Chapters.

USP anticipates that a second draft of the proposed General Notices will be available at the USP Annual Science Meeting, Sept. 25–28, 2007. USP anticipates publishing this second draft on the USP website for comment and in Pharmacopeial Forum 33(6) in November 2007. The comment period will close on Feb. 15, 2008.

Revising the General Notices is a timely and thoughtful activity that USP is undertaking at the urging of its volunteer community and constituents, whom we thank in advance for their participation.
