When a title is issued in multiple series, BIBFRAME does not have a way to associate each series with its numbering. For example, looking at OCLC #45898, as converted by the LC program, we find the following. BIBFRAME Work bf:hasSeries <http://lib.washington.edu/ld/test/99130299090001452#Work830-36>, <http://lib.washington.edu/ld/test/99130299090001452#Work830-37> ; bf:seriesEnumeration "43", "7902" ; BIBFRAME Instance bf:seriesEnumeration "43", "7902." ; bf:seriesStatement "African series", "Department of State publication" ; In neither the Work nor the Instance can enumeration be associated with its series for the purpose of search or display. This is a significant step back from current practice.
