           Summary: Improving links to find analytics and volumes when
                    using UseControlnumber

There are cases when both links "Show analytics" and "Show volumes" will show
up on a record. At the moment the link for both is the same, searching for all
records with the 001 of the record in a $w subfield of other records.

By using the bib-level index the search links can be made more precise, so
"Show analytics" will only bring up analytical records while "Show volumes"
will find the linked volumes and monographical records.

Bib-level is the index on LDR pos. 7:
- For analytics: a, b
- For Volumes: everything except a, b

A record showing both links is:
- A serial: LDR pos. 7 = s
- Part of a traced series: LDR, pos. 19 = a or a monographic series 008,
Continuing resource, pos. 21 = m
