=item @recl = $lr->record([$rec])
Returns the record list and optionally adds a new record or resumptionToken, $rec. Returns an array ref of L<HTTP::OAI::Record|HTTP::OAI::Record>s, including an optional resumptionToken string.
=item $token = $lr->resumptionToken([$token])
Returns and optionally sets the L<HTTP::OAI::ResumptionToken|HTTP::OAI::ResumptionToken>.
=item $dom = $lr->toDOM
Returns a XML::DOM object representing the ListRecords response.
