[Placeholder slide: ideas to cover here] • Examples of applying Cutter table from Steven’s Shelflisting draft, slides 12-15 • Example of resulting call number needing to be adjusted because of works already shelflisted • How many Cutters? • Exercises: using the table to construct Cutter numbers
Additions to call numbers • Date of publication is added in most cases • Work letter (or mark) • Terms such as Index or Suppl. • Local decisions: • Copy 1, 2, etc. • Oversize designation
Display of the notation • The same LC call number may be displayed in numerous ways RC RC RC569 RC569.5 569.5 569.5 .5 .S56B36 .S56 .S56B36 .S56B36 1988 B36 1988 1988 1988

MARC Coding in RLIN • [not sure what the practices are; need help from an RLIN member]
[Placeholder slide: ideas for more shelflisting] • These are concepts I’m not sure are covered anywhere else, in no particular order • Double-Cutters, both extend class number • Reserved Cutters (A and Z) • Cuttering for numerals • “under each” subarrangements .x and .x2 • Filing order, inserting the number • More on dates
