LKR - ALEPH Linking Field (R)
No Indicators
Subfield Codes $$a - link type UP link to another BIB type record. A record can have only one link of this type. "DN" link is automatically built in the opposite direction. DN "down" link to another BIB type record. Multiple links are possible. "UP link is automatically built in the opposite direction. PAR parallel link from BIB record to BIB record. "PAR" link is automatically built in the opposite direction. HOL link from HOL record to BIB record. Link is built from BIB to HOL. ADM link from ADM record to BIB record. Link is built from BIB to ADM. ANA is a link between bibliographic records of different levels. When an analytic link is created the system generates UP / DWN links between the two records and an item link between the source record and the item that corresponds to it (according to vol.,part, year and pages) on the ADM record of the second record. ITM links are created between a Bibliographic record and an ADM record when there is no relationship between the two Bib records, for example when two items are bound together. $$b - sysno of the linked document record $$l - library where linked record is located $$n - note regarding a DN (down record) link $$m - note regarding an UP (up record) link $$y - analytic link - year link $$v - analytic link - volume link $$p - analytic link - part link $$i - analytic link - issue link $$k - analytic link - pages $$s - Sort Sequence - Can be alphanumeric (1,2,3... or a,b,c...)
