Plus data source and adds any new review sources to the local record. You
can use this option to enhance your local full bibliographic records by adding
interest and reading levels or to update local records previously processed
with an older Alliance Plus data source.
Note: Your patrons can use the reading and interest levels to limit the scope
of searches conducted with OPAC. See page 470 for more information.
Bibliographic record modifications
The following sections describe how Alliance Plus modifies bibliographic records
during the Autorecon process. Refer to the section that applies to the Autorecon
process option in question.
Replace brief or full bibliographic records
When Alliance Plus finds a data source record that matches a record in the library
database, it deletes all the tags from the local record with exception of the
following locallyĆdefined tags:
S 521 S 790-799
S 526 S 856
S 590-599 S 900-939
S 658 S 941-999
S 690-699
It then inserts new tags from the matching record on the Alliance Plus data
source, and copies the information from the local 001 and 003 tags to the new 035
tag. If the record doesn't have a 003 tag, it copies the contents from the 040 tag
instead. The 035 tag contains the system control number and identifies the record
as being from another computer system.
Alliance Plus also copies reading and interest level and review source
information from the data source record's 940 tag into the library record. The
application follows the current MARC 21 standard by storing the copied
information in subfield a of each of the following tags:
Information Library record tag
Review source 510
Note: Since the subfields in the 510 tag are not repeatable, Alliance
Plus adds a separate 510 tag for each review source stored in the 940
tag.
Reading level 521 (first indicator: 0)
Interest level 521 (first indicator: 2)
Update review sources and reading/interest levels
Alliance Plus compares the reading and interest level and review source
information in each library bibliographic record against the information in the
