The proposed changes to subheadings in MEDLINE by the National Library of Medicine has created quite a stir. (Krafty Librarian post March 27, 2006) The Senior Technical Information Specialist, MeSH - Medical Subject Headings Section of the US National Library of Medicine forwarded a background paper on the topic to MEDLIB-L.

(forwarded from MEDLIB-L)
A background paper which also contains the lists of proposed qualifer arrays, qualifers to be deleted with proposed mapping, and alphabetic list of all qualifiers has been made available at

The period for comments regarding the change has been extended to April 14, 2006.
