$$a - link type
UP link to another BIB type record. A record can have only one
link of this type. "DN" link is automatically built in the
opposite direction.
DN "down" link to another BIB type record. Multiple links
are possible. "UP link is automatically built in the
opposite direction.
PAR parallel link from BIB record to BIB record.
"PAR" link is automatically built in the opposite direction.
HOL link from HOL record to BIB record. Link is built from
BIB to HOL.
ADM link from ADM record to BIB record. Link is built from
BIB to ADM.
ANA is a link between bibliographic records of different levels.
When an anayltic link is created the system generates UP / DWN
links between the two records and an itm link between the source
record and the item that corresponds to it (according to vol.,part
year and pages) on the ADM record of the second record.
ITM links are created between a Bibliographic record and an ADM
record when there is no relationship between the two Bib records,
for example when two items are bound together.
