Maria P. P. Root’s “A Bill of Rights for
Racially Mixed People”
“I have the right
to identify myself differently than strangers expect me to
identify
to identify myself differently than how my parents identify me
to identify myself differently in different situations”
“I have the right
to create a vocabulary to communicate about being multiracial
to change my identity over my lifetime—and more than once”
Jonathan Furner: The Challenge of the Selfidentity Principle (1)
Designers of library catalogs and classification schemes have
a responsibility to ensure:
(i) terminology used to represent racially mixed people
reflects the terminology used by racially mixed searchers
to identify themselves
(ii) works about racially mixed people can be retrieved in
any of four ways that they may identify themselves
Jonathan Furner: The Challenge of the Selfidentity Principle (2)
Racially mixed people may identify themselves:
1. with racially mixed people generally;
2. with racially mixed people particularly;
3. with several racial populations equally; or
4. with one racial population separately.
Table 5 Notation in the Context of DDC as a
Whole
Appears at the end of a standard Dewey number, or
embedded in the middle
May be omitted if the number is long
Various rules may prevent Table 5 notation from
being added, e.g., requirement that the topic
approximate the whole
Can never be added for literary works by individual
authors

Mapping Subject Headings to Table 5

fields of bibliographic records

DeweyBrowser beta v2.0 and Table 5
The DDC summaries are presented in a tag cloud
(without notation) in DeweyBrowser beta v2.0,
available at
http://deweybrowser.oclc.org/ddcbrowser2/
Table 5 topics might be presented in an alternative
tag cloud of terms
Table 5 Topics and Tag Clouds
Some broad Table 5 topics would be useful in a tag
cloud, e.g., North American native peoples
Others would be skipped, e.g., Other Indo-European
peoples
Narrower topics could be promoted to the opening
tag cloud in place of the skipped topics, e.g., Irish
Captions could be modified, e.g., Racially mixed
people for Table 5 notation 05
Conclusion: Part (i) of the Challenge:
Terminology
Present multiple names for the same Table 5 topic in
a tag cloud? No!
Then we cannot allow each searcher to search on
that individual’s preferred term
Maybe some day a searcher will be able to
personalize the names of the tags in a tag cloud
Conclusion: Part (ii) of the Challenge:
Retrieval
Creative use of Table 5 notation in the MARC Bibliographic
format 083 field can improve retrieval
Searchers who identify (1) “with racially mixed people
generally” and (4) “with one racial population separately”
will fare best
Searchers who identify (3) “with several racial populations
equally” will probably be willing to do successive searches
Searchers who identify (2) “with racially mixed people
particularly” will need to use Boolean searches
