Implementation of Change in Indicator Value for Multiple Surnames
In 1996, the first indicator value 2 (Multiple surname) in X00
fields was made obsolete. Value 1 (Single surname) was redefined
as "surname" to be used for headings with either single or multiple
surnames. At the time value 2 was made obsolete, LC had an
arrangement with an outside source to update existing authority
records programmatically to change all instances of value 2 to
value 1 in X00 fields; these updated records were then to have been
made available to other libraries through distribution from LC. LC
was recently informed by that source that it would be unable to
execute this change. In view of this development, the Library of
Congress has had to reassess its implementation strategy.
LC/NACO libraries will defer implementing discontinuing use of
value 2 in X00 fields until some time after installation of an
Integrated Library System (ILS) at the Library of Congress; that
installation is now scheduled for October 1, 1999. There are two
exceptions to this policy as it relates to current records
contributed by the British Library (BL) and to retrospective
records from the Dance Heritage Coalition (see below).
The Library realizes that this decision may have an impact on the
library community, but, after considering various alternatives, it
became clear that the Library has neither the human nor machine
resources to change the entire authority database manually or
BRITISH LIBRARY RECORDS
Based on LC's original plan to implement the change in 1998, the BL
announced that it has implemented the change on January 2, 1998.
The LC/NACO practice will take this implementation into account
DANCE HERITAGE COALITION RECORDS
Approximately 52,000 retrospective records from the Dance Heritage
Coalition were recently loaded into the name authority file, some
of which represent headings for multiple surnames. At the time
they were being processed for loading, these headings contained a
first indicator value of 1. Since at that time we had anticipated
making the programmatic change described above, the decision was
made to leave the indicator value at 1. The LC/NACO practice will
take these records into account (see below).
LC/NACO policy is to continue to use first indicator value 2 for
multiple surnames except as noted below.
In the normal course of searching the name authority file, be
particularly conscious of the first indicator value with a view to
preserving any X00 character strings for multiple surnames
containing value 1 in records contributed by the British Library or
the Dance Heritage Coalition; preserving the relationship between
the character string in a bibliographic record and that in the name
In essence, this practice means that LC/NACO libraries will
continue to use value 2 in both authority and bibliographic records
except for multiple surnames represented by authority records
contributed by the BL or the Dance Heritage Coalition. Also, if
adding a multiple surname reference to one of those records, use
value 1 to preserve the internal integrity of the authority record.
If adding one of those names to a new or existing bibliographic
record, use value 1 to preserve the consistent relationship between
the character string in the bibliographic record and that in the
name authority record.
Note that this practice will result in bibliographic records
that may contain multiple surnames
with a mixture of indicator values, that is some with 2 and some
