Serials Issued in Microform

Serials may be issued in microfilm in two ways originally as microform or as a reproduction of the original print or some other original format. Original microforms, also called micropublications, are first issued in a micro format, rather than reproduced from a printed manifestation. A reproduction microform is a work having a bibliographic and/or physical identity which existed prior to the microform.  Determining mode of issuance is critical as it will determine the rules applied to the cataloging of the microform.
