Bibliographies and Related Materials
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.
Within 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.

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
