For serial (10) maps, the word year is placed in the date/scale area of the call number in the cataloging record. On the item themselves, however, the call number is written to include the appropriate date of situation for each sheet. Example:

Scale Symbol (11):

For map series/sets the call number 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. an s precedes the scale indicator to distinguish it from a date in a call number. There is no rounding of the numbers.

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). Example:

For a map series/set composed of maps for which the scale is not expressed as, or based on, a representative fraction (e.g., Scale not given, Not drawn to scale, or a non-linear scale) use the designation s000 as the scale value in the call number.

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

For map set/series composed of maps drawn at two different scales, select the predominant scale that best characterizes the scope and content of the map set/series as the basis for determining the scale value for the call number. However, if neither scale is clearly predominate prefer the larger scale (i.e., smaller number) as the basis for determining the scale value for the call number.

For map series/sets composed of items drawn at more than two scales (i.e., Scales differ) use svar as the scale value in the call number. Examples:

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