NLM Classification 2013 Edition

Willis SR. NLM Classification 2013 Edition. NLM Tech Bull. 2013 May-Jun;(392):e1.

2013 May 01 [posted]

The NLM Classification, available online at http://www.nlm.nih.gov/class/, incorporates all additions and changes to the schedules and index from April 2012 through March 2013. The PDF version will be updated with 2013 classification data by the end of May 2013.

The QU (Biochemistry. Cell Biology and Genetics) schedule was the major area of focus for the 2013 edition.  

Background: With the 2005 edition of the NLM Classification, NLM established a new range of numbers in QU for cells (QU 300-400) and genetic concepts (QU 450-500). These topics were formerly scattered in various numbers in the Library of Congress general biology schedule, QH.  When the genetic terms were brought into the NLM schedule, they were split between the QU schedule and the QZ (Pathology) schedule (for clinical aspects).

With the 2013 edition:

In addition:

Class Numbers Added and Canceled

Thirty-two (32) new class numbers were added.  No class numbers were canceled.

Table G (Geographic Notations)


Changes were made to Table G (Geographic Notations):
One Table G number was added: GB1-- Balkan Peninsula

Other Changes to the Schedule


Changes were made to other class schedules. For example:
  • At QZ 42, Adverse effects of drugs was removed from the caption.
  • At QZ 50, Heredity. Medical genetics was changed to Heredity. Genetic causes of disease.
  • At QZ 52, Genetic techniques was changed to Genetic testing.
  • At WG 141.5.A3, Angiocardiography. Angioscopy was changed to Angiography. Angioscopy.
  • At WG 500, Radiography was removed from the caption.
  • The schedule outline WR 650-670 Therapy was added.
  • At WX 162, the caption was changed from Patient care planning. Progressive patient care. Long-term care to Hospital care. Patient care planning. Long-term care.
  • Instructional notes were added or modified to clarify classification practices as needed.  For example:
    • A note was added to QY 95: Classify techniques associated with a specific type of cell with the cell.
    • A note was added to WG 169: Classify works on cardiac anesthesia in WG 460.
  • Table G (geographic breakdown) is now permitted with W 76.

All index entries pertaining to the aforementioned schedule additions and changes were modified.
