ephemera: Printed matter of passing interest.*
Paper materials that don't qualify as publications, typically not meant to be saved (thus the passing interest). Advertisements, letters, announcement sheets, contact lists, order forms, etc.
Not even under construction yet (though some ephemera is in the Fanzines, Newsletters, Journals section, to be moved over here when the next organizational pass occurs).
