Scale Symbol (2)

The call number for a map series/set includes an indication of scale in place of the date of information. The scale symbol is derived by dropping the last three digits from the denominator of the representative fraction. There is no rounding of the numbers

An s precedes the scale indicator to distinguish it from a date.

The scale symbol is transcribed in the call number without commas, regardless of the number of digits.

For map series/sets at scales larger than 1:1,000 the denominator of the fraction is treated as a decimal and is preceded by zero(s). Examples:

When a map series/set is composed of maps that do not have a scale expressed as a representative fraction (e.g., Scale not given, Not drawn to scale, a non-linear scale, etc.), use the designation s000 as the scale indicator in the call number. This designation will file ahead of all other scale indicators. Example:

In arranging items by call number (i.e., shelflist order), this designation precedes all other scale indicators.

When a map series/set is composed of maps drawn at two different scales, select the predominate scale (i.e., the one that best characterized the scope and content) as the basis for determining the call number scale indicator.

When a map series./set is composed of maps drawn at more than two scales (i.e., Scales differ) use svar as the scale indicator in the call number. Examples:

In arranging items by call number (i.e., shelflist order), this designation follows all other scale indicators.

The word year is used in the date/scale area of the call number in bibliographic records for serial (3) On the individual items, however, the call number is written to include the appropriate date of situation for each sheet. Example:

In arranging items for call number (i.e., shelflist order) this designation precedes all specific dates and all scale designations.
