  1. NLM Classification {National Library of Medicine} Rebecca Mieure Sharon Robinson Stephanie Tilt Emporia State University

  2. What is the NLM Classification?

  3. What is NLM Classification? Patterned after the Library of Congress Classification System It covers the field of medicine and related sciences A broad classification that is suitable for both large and small library collections It may be adapted to handle specialized collections of any size

  4. http://www.nlm.nih.gov/class/nlmclasspost.html http://www.nlm.nih.gov/class/nlmclasspost.html

  5. How is the NLM Classification Organized? Preclinical Sciences (QS-QZ) General Health and Medicine (W-WB) Diseases of the Whole Body; Aviation, Space, Naval Medicine (WC-WD) Body Systems (WE-WL) Specialty Areas (WM-WY) History (WZ and 19th century schedule)

  6. How is the NLM Classification Organized? QS-QZ, W-WY, and WZ (excluding 220-270) are used to classify works published after 1913 The 19th Century schedule is used for works published from 1801-1913 WZ 220-270 is used for works published before 1801 and Americana Table G subdivides certain subjects by geographic location

  7. LCC Schedules Not Used by NLM QM: Human Anatomy (NLM uses QS) QR: Microbiology (NLM uses QW) R: Medicine (NLM uses QT-QZ and W-WZ)

  8. NLM Index Index headings are MeSH Arranged in alphabetical order Includes NLM classification numbers for medical concepts Many headings are assigned a range of numbers rather than a specific number Updated annually to reflect MeSH changes

  9. History of NLM Updates Print edition (1951-1999): infrequently Online edition (2002 - present): annually PDF (2006 - present): annually NLM Poster (2005 - present): as needed

  10. New Revision: April 28, 2011 46 New class numbers added 3 class numbers deleted 69 MeSH terms added to the index, including 41 new to the MeSH vocabulary as of 2011 178 class number captions or schedule notes modified 606 index entries modified

  12. History of the National Library of Medicine

  13. Joseph Lovell 1836

  14. Ford’s Theatre

  15. Report of a Survey of the Army Medical Library (1944) Improve Facilities Products Services Staffing Support for increased funding Major changes in operations

  16. NLM Classification “The genesis of the NLM classsificationis a Survey Report on the Army Medical Library, published in 1944, which recommended that the “Library be re-classified according to a modern scheme,” and that new scheme be a mixed notation (letters and numbers) resembling that of the Library of Congress.” http://www.nlm.nih.gov/class/nlmclassintro.html

  17. NLM Classification Mary Louise Marshall produced the rough draft for the NLM classification (1949) Frank B. Rogers revised the rough draft and the NLM was published in 1951

  18. How it is Used and Who is Using it

  19. How and Who? WORLD’s largest medical library Medical Libraries –Over 400 in mid-continental (UT, WY, KS, NE Health Professionals –Doctors, etc. Med students Patients http://youtu.be/CpYvQAc8e4w High school students http://www.youtube.com/watch?v=4-aptav5urI

  20. NLM Resources NLM website (http://www.nlm.nih.gov/) provides: Over 100 Databases – ie. PubMed (under Databases heading) History of Medicine (under Explore NLM heading) Various Research projects (under Research at NLM heading)

  21. More Resources Grants, Training/research, and jobs (NLM for You heading) Read about diseases, drugs, find clinical trials (Find, Read, Learn) NLM News and Events Podcasts

  22. Trivia Questions: • According to the NLM classification table what heading and number would plant poisons be under? • Disorders of Systematic, Metabolic, or Environmental Origin, etc. W D 400-430 • Find the podcast “The Gulf Oil Spill's Health Impact” • http://www.nlm.nih.gov/medlineplus/directorscomments.html • What are the hours of the National Library of Medicine? • M-F 8:30 am – 5:00 pm Sat. 8:30 – 2:00 pm closed Sun

  23. Hmmm… Effectiveness, would we change anything? We didn’t feel we had enough medical knowledge to really have a decent question on its effectiveness Classification starts at QS –WZ (why these letters? Seems confusing to “normal people”)

  24. Evaluation of NLM Classification System Majority of medical libraries use the NLM classification system because the “system is the most detailed and the most appropriate for a medical collection and that provides the best coverage for the subject area.” (Womack, 2006, p. 106)

  25. Other Reasons to use it Browsing Traditional System/familiar Conform/independent

  26. MeSH (Medical Subject Heading) “Best and most appropriate controlled vocabulary system for a medical collection” MEDLINE Familiar/Different MeSH uses vocabulary medical professionals use LCSH vocabulary matches consumers terms. (Womack, 2006, p. 107-108)
