--format=FORMAT FORMAT is either 'xml' or 'marc' (default)

--date=DATE DATE should be entered as the 'dateformat' syspref is

set (dd/mm/yyyy for metric, yyyy-mm-dd for iso,

mm/dd/yyyy for us) records exported are the ones that

have been modified since DATE

--record-type=TYPE TYPE is 'bibs' or 'auths'
|
|
|
|
--deleted_barcodes If used, a list of barcodes of items deleted since DATE
|

is produced (or from all deleted items if no date is
|
|
specified). Used only if TYPE is 'bibs'
|
|
|
|
--clean removes NSE/NSB
|
|
|
|
--id_list_file=PATH PATH is a path to a file containing a list of
|
|
IDs (biblionumber or authid) with one ID per line.
|
|
This list works as a filter; it is compatible with
|
|
other parameters for selecting records
