## Some background about MARC as understood by this script
|
|
## The default input format used in this script is MARC21, which
|
|
## superseded USMARC and CANMARC. The specification can be found at:
|
|
## http://lcweb.loc.gov/marc/
|
|
## UNIMARC follows the specification at:
|
|
## http://www.ifla.org/VI/3/p1996-1/sec-uni.htm
|
|
## UKMARC support is a bit shaky because there is no specification available
|
|
## for free. The wisdom used in this script was taken from a PDF document
|
|
## comparing UKMARC to MARC21 found at:
|
|
## www.bl.uk/services/bibliographic/marcchange.pdf
