The date of publication field
This field identifies the stated date of publication of a book, catalogue, periodical, CD, or other such material. Other information about the date of publication (for example, that the item may not have been issued on the stated date) will be included in the notes field.
The format for dates is YYYY-MM-DD.
Caution:
Publications dated by season or other span of time cannot be identified as such in the date field because of technical limitations in the program used to create this catalogue. Therefore, when needed, an approximate date (described below) will be entered in the date field, while the actual stated date of publication will be cited in the notes field.
Publications dated by season will be entered in the date field by the first month in which a given season begins. Examples are:
For a publication dated 1989 Spring, the date field will read 1989-03-00;
For a publication dated 1989 Summer, the date field will read 1989-06-00;
For a publication dated 1989 Fall (or Autumn), the date field will read 1989-09-00;
For a publication dated 1989 Winter, the date field will read either 1989-12-00 or 1989-01-00. (The compilers assume that Winter issues appear at the end of the year rather than at the beginning, unless we have information that suggests otherwise.)
Publications listing a date that spans a time period other than a single season will be entered in the date field by the earliest given date. Examples are:
1989 Spring-Summer will be entered in the date field as 1989-03-00;
1989-1990 will be entered in the date field as 1989-00-00;
1989 April 27-May 13 will be entered in the date field as 1989-04-27.
Please be sure to check the notes field to ensure that you have the accurate date for a publication.
You may search the catalogue for items starting from a given date, up to a given date, or between two dates:
¨ If you fill in only the From component of the date of publication field, your search will return all the material published from and including the date you selected up to the most recent date in the catalogue.
¨ If you fill in only the To component of the date of publication field, your search will return all the material published from the earliest date in the catalogue up to and including the date you selected.
¨ If you select From 1985-00-00, To 1985-00-00, your search will return all the material published between 1985-01-01 and 1985-12-31, including material for which the date of publication is given as 1985-00-00.
¨ However, if you select From 1985-01-01, To 1985-12-31, your search will return all the material published between and including those dates, but will not include material for which the publication date is given as 1985-00-00.
¨ If you select From 1979-04-24, To 1979-04-24, your search will return only the material whose stated date of publication is that exact day.
