The copyright duration rules for different material types may require the publication or creation date for a work. The following rules are used to extract these dates from a catalogue record.
The following rules show how we determine the creation and publication dates from a MARC record. To understand these rules, you will need to have a basic understanding of the MARC standard for bibliographic records. If you don't know MARC, you could try this tutorial.
Use 008 field character positions 7-10 (date one) and 11-14 (date two) to determine creation/publication dates. The type of date represented by date one and date two depends on the code in 008 field character position 6, which represents the type of date/publication status.
008 character position 6 |
use of dates |
---|---|
b - No dates given; B.C. date involved |
copyright status = out of copyright |
c - Continuing resource currently published |
copyright status = undetermined, because the catalogue record represents a series of items with a range of publication dates |
d - Continuing resource ceased publication |
use date two (008/11-14) as creation/publication year, because it represents the most recent date of publication |
e - Detailed date |
use date one (008/7-10) as creation/publication year |
i - Inclusive dates of collection |
use date two (008/11-14) as creation/publication year, because it represents the most recent date of publication |
k - Range of years of bulk of collection |
copyright status = undetermined, because the catalogue record represents a series of items with a range of publication dates |
m - Multiple dates |
use date two (008/11-14) as creation/publication year, because it represents the most recent date of publication |
n - Dates unknown |
copyright status = undetermined, because no creation/publication date is recorded |
p - Date of distribution/release/issue and production/recording session when different |
use date two (008/11-14) as creation/original publication date and date one (008/7-10) as later edition date |
q - Questionable date |
use date two (008/11-14) as creation/publication year, because it represents the most recent date of publication |
r - Reprint/reissue date and original date |
use date two (008/11-14) as creation/publication year (original date) and date one (008/7-10) as later edition date |
|
use date one (008/7-10) as creation/publication date |
t - Publication date and copyright date |
use date two (008/11-14) as creation/publication year, because it represents the most recent date of publication |
u - Continuing resource status unknown |
copyright status = undetermined, because the end date is unknown |
| - No attempt to code |
copyright status = undetermined, because no creation/publication date is recorded |
N.B. Uncertain date: For any of the above, if 008/7-14 contain "u", date is uncertain. If an expected date in 008/11-14 is missing (blank), use the date in 008/07-10, but if both are blank (unlikely), date is uncertain. If date in 008/11-14 is "9999", this signifies an uncertain date or a range of dates with an open end date (e.g. continuing serial publication) - in this case display the message Created/published date is uncertain, there may be multiple dates.
