Dealing with Unknowns
nInformation is unknown
–E.g. photo with no information about photographer, location, date
nInformation is not provided in metadata
–E.g. archive was unable to examine each piece
nInformation exists but is not for public display
–“Contact archive for more information”
User service value – is it worth going back to the archive to obtain more information? The “contact archive” method is quite costly to users, and often does not result in more information. Need to know if archive has provided all that they have.
