DATING FIELDS
Comments
Edits were made to this field in May 2010. Data entry rules were made more precise, and harmonized with those recommended in Cataloging Cultural Objects: A Guide to Describing Cultural Works and Their Images. By Murtha Baca, Patricia Harpring, Elisa Lanzi, Linda McRae, and Ann Whiteside. Visual Resources Association. Chicago: American Library Association, 2006. Website: http://www.vrafoundation.org/ccoweb/index.htm (accessed 2010-03-05).
Entry rules
Enter a numeric date. Do not use multiple entries. Record years without commas or other punctuation, except for the dash, which is used to express negative numbers for dates BCE. Use four digits for most years. If possible, for years that require fewer than four digits, insert leading zeroes (for example, 0009). Dates BCE may require more than four digits (for example, -10000). If the year alone is not precise enough, record a more precise date, using the following format if possible: YYYY-MM-DD. However, international standards suggest alternate possibilities; an alternate syntax (e.g. YYYYMMDD) may be used if it is consistent and it is compliant with the ISO standard . Local rules should be enforced. Do not use n.d. to indicate no date. If the specific year or years is not known, record dates with the greatest accuracy known. If a date is uncertain, determine a possible date range based on available information.
Cataloguers rules
If only one date is known for the object, then use Date of Object, To (EPD2). If a date range is known, enter the earliest date in Date of Object, From (BPD1) and the most recent date in Date of Object, To (EPD2). If only a date range is known for the earliest date, then enter the lower value in Date of Object, From (BPD1) and the higher value in Date of Object, From (2) (BPD2). Similarly, if only a date range is known for the most recent date, then enter the less recent date in Date of Object, To (1) (EPD1) and the more recent date in Date of Object, To (EPD2). BP dates should be converted to BCE dates. See also, Date of Object, From (2) (BPD2), Date of Object, To (1) (EPD1), Date of Object, To (EPD2), Period (PER) and Absolute Date (ABD).
