Read-Staff-Journal names a function, with lambda list (&KEY (START-DATE (YESTERDAY)) (END-DATE (NOW)) LAST):
Read staff journal entries between (inclusive) START-DATE and END-DATE; default, yesterday and today.
Or, read the single item LAST from the end; when LAST = 0, the very latest entry; when LAST < 0, then the “nth” entry from the end. Thus, -1 is the next-to-last entry, -2 is the third from the end.
