Bibliography

• Publications (monographs and serials) consisting of bibliographies are classed by subject

• Select the classification number that best fits the overall topic of the bibliography and which corresponds to the primary subject heading assigned (Cf. Module 4—General Principles)

Class Number within the Scope of the NLM Classification

• If the class number falls within the scope of the NLM Classification, preface the class number with a capital "Z" with no space in between the letter "Z" and the other letters

• Example:
  • A monograph with lists of works on chronic disease
    • 060 00 $a ZQZ 185
    • 650 12 $a Chronic Disease
    • 655   2 $a Bibliography

• Exceptions:
  • A bibliography of a single author’s work is classed in WZ 100
  • A bibliography of commentaries on a single work is classed in WZ 294

Class Number outside the scope of the NLM Classification

• If the class number falls outside the scope of the NLM Classification, generally use the LCC Z schedule for bibliography, Z 1001-Z 9000, with a space in between the letter "Z" and the number

• Example:
  • A monograph with lists of works on information sources in science
    • 060 00 $a Z 7401
    • 650 12 $a Science
    • 655   2 $a Bibliography

• Exception: ZSF [and number] is used for subjects in the LCC SF schedule

• Example:
  • A research bibliography on cat diseases
    • 060 00 $a ZSF 985
    • 650 12 $a Cat Diseases
    • 655   2 $a Bibliography
