access date
n.
The date when records that have been closed or restricted become generally available for use by the public.
A time stamp associated with a file indicating the last time the file was viewed.
The portion of a bibliographic citation for a website indicating when the page, as cited, was known to be current.
Notes
Access dates1 are usually determined by a set period of time. - Access date2 differs from the date the file was created and from the date the file was last updated; not all computer operating systems or databases track access date. - Access dates3 document the version of a website used as the source; the frequency of change and disappearance of web pages makes the date particularly important.
