See the following website for an outline of the NLM classification http://www.nlm.nih.gov/class/OutlineofNLMClassificationSchedule.htmlFor the actual table go here: http://www.nlm.nih.gov/class/nlmclasspost.html4How 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)How is the NLM Classification Organized?QS-QZ, W-WY, and WZ (excluding 220-270) are used to classify works published after 1913The 19th Century schedule is used for works published from 1801-1913WZ 220-270 is used for works published before 1801 and AmericanaTable G subdivides certain subjects by geographic location

LCC Schedules Not Used by NLMQM: Human Anatomy (NLM uses QS)

QR: Microbiology (NLM uses QW)

R: Medicine (NLM uses QT-QZ and W-WZ)NLM IndexIndex headings are MeSHArranged in alphabetical orderIncludes NLM classification numbers for medical conceptsMany headings are assigned a range of numbers rather than a specific numberUpdated annually to reflect MeSH changes

NLM ClassificationThe genesis of the NLM classsification is 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.

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

Hmmm Effectiveness, would we change anything?We didnt 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)

24Evaluation of NLM Classification SystemMajority 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.
