1LaBarre, K. ; Cochrane, P.A.: Facet analysis as a knowledge management tool on the Internet.
In: Knowledge organization, information systems and other essays: Professor A. Neelameghan Festschrift. Ed. by K.S. Raghavan and K.N. Prasad. New Delhi : Ess Ess Publications, 2006. S.53-70.
Abstract: In 2001, a group of information architects involved in designing websites, and knowledge management specialists involved in creating access to corporate knowledge bases appeared to have re-discovered facet analysis and faceted classification. These groups have been instrumental in creating new and different ways of handling digital content of the Internet. Some of these practitioners explicitly use the forms and language of facet analysis and faceted classification, while others seem to do so implicitly. Following a brief overview of the work and discussions on facets and faceted classification in recent years, we focus on our observations about new information resources which seem more in line with the Fourth law of Library Science ("Save the time of the reader") than most library OPACs today. These new developments on the Internet point to a partial grasp of a disciplined approach to subject access. This is where Ranganathan and Neelameghan's approach needs to be reviewed for the new audience of information system designers. A report on the work undertaken by us forms a principal part of this paper.

2Owens, L.A. ; Cochrane, P.A.: Thesaurus evaluation.
In: Cataloging and classification quarterly. 37(2004) nos.3/4, S.xx-xx.
Abstract: The process of thesaurus evaluation can enhance the value of a thesaurus in terms of usability, scope, precision and recall. Structural, formative, observational and comparative evaluation techniques are explained along with specific examples of their use. These methods of evaluation can be applied in the assessment of an existing thesaurus or the construction of a new thesaurus. The history of thesauri since 1960, the development of national and international standards, and sources of evaluative literature are also discussed.

In: The LCSH century: one hundred years with the Library of Congress Subject Headings system. Ed.: A.T. Stone. New York : Haworth Press, 2000. S.73-89.
(Cataloging and classification quarterly; vol.29, nos.1/2)
Abstract: In 1986 Libraries Unlimited published Cochrane's book, Improving LCSH for Use in Online Catalogs; Exercises for Self-Help with a Selection of Background Readings. This was preceded in 1981 by an ERIC publication (ED 208 900) by Cochrane, with Monika Kirtland Bibliographic and Bibliometric Essay which documented critical views of LCSH and an analysis of vocabulary control in LCSH (parts of which were published in Cataloging & Classification Quarterly' 1(2/3) (1982), 71-94). Three features of LCSH will be re-examined to check on progress since the time of these earlier publications: notes, structure of relationships between headings in the list, and links between Library of Congress classification numbers and LCSH or other vocabularies

4Smith, M.J. ; Cochrane, P.A.: Creating better subject access with multiple vocabularies : upgrading the Subject Heading List for the Alzheimer's Association.
In: Library resources and technical services. 43(1999) no.1, S.53-58.
Abstract: Although the Alzheimer's Association's Green-Field Library's catalog has been available to local chapters and interested people for some time through modem access, placing the catalog on the World Wide Web would make it available to casual browsers as well as determined searchers. When a review of the subject list revealed numerous inconsistencies and duplications, a new list was generated, giving preference to Medical Subject Headings (MeSH) where possible. The result was a mix of MeSH and Library of Congress Subject Headings (LCSH), augmented by a few local- and reviewer-supplied terms. The new subject authority list gives the Green-Field Library an authoritative list of terms to use when performing original and copy cataloging. It can also be placed with the library's catalog on the Web to aid users in performing searches.

7Cochrane, P.A. ; Johnson, E.H.: Visual Dewey : DDC in a hypertextual browser for the library user.
In: Knowledge organization and change: Proceedings of the Fourth International ISKO Conference, 15-18 July 1996, Library of Congress, Washington, DC. Ed.: R. Green. Frankfurt : INDEKS, 1996. S.95-106.
(Advances in knowledge organization; vol.5)
Abstract: A new design for the DDC allows for display of the schedules and indexes in a hypertextual browser which was originally designed for the more conventional thesaurus with BT-NT, RT and USE-UF relations. Features of the DDC which approxumate those relations and the presentation of the rich vocabulary found in the hierarchical structure, captions, index entries and notes are represented for the library user's perusal and choice before searching a library's holdings. By dragging and dropping parts from such a display into a search window, the search for bibliographic items can begin and revised painlessly. Information such as class numbers of subject headings for retrieved items can be dragged and dropped into the searchw indow of the Visual Dewey display window as it suits the user to review vocabulary or revise the search results. This seamless to-ing and fro-ing allows for a truly interactive and spontaneous search environment, with maximum assistance at point of need. 'File folders' exist for saving any Visual Dewey information, any retrieved items, etc.

9Cochrane, P.A.: New roles for classification in libraries and information networks.
In: Cataloging and classification quarterly. 21(1995) no.2, S.3-4.
Inhalt: The 36th Allerton Institute, sponsored by the University of Illinois Urbana-Champaign Graduate School of Library and Information Science was held at the University of Illinois Conference Center near Monticello, Illinois on October 23-25, 1994. The theme centered around new roles for library classification in the electronic age. Representatives of six of the world's most used library classifications presented papers and demonstrations to show how traditional uses for shelf arrangement will be expanded to include uses on the Internet, World Wide Web, Library homepages and in other networks. Several of these papers will be included in this issue of Cataloging & Classification Quarterly: Joan S. Mitchell for Dewey Decimal Classification (DDC), Ia Mcllwaine for the Universal Decimal Classification (UDC), Eric Coates for both the Broad System of Ordering (BSO) and the Bliss Classification (BC). (Other issues of this journal will cover the National Library of Medicine and Library of Congress Classification.) An international trio of keynote addresses by Lois Chan, Ingetraut Dahlberg, and Pat Moholt faced the future and found several roles for library classification systems if they can match the growing need for organization of electronic resources. Several panels representing varying viewpoints was the vehicle for hearing from participants at the Allerton Conference. Some of these discussions were covered by student reporters and are included in this issue (Ann Marie Ziadie for the discussion of networks abroad; Shirley Lincicum for those discussing non-traditional uses of classification; and Brendan Wyly for those focusing on information networks). Janet Swan Hill's paper, included here, is representative of the panel of library administrators. The closing remarks by Marcia Bates and Sarah Thomas pointed to a dozen directional signals for those interested in a more meaningful role for library classification in the world of electronic information resources: ; 1. Exploit technology a. for adding class numbers to materials in digital form. b. for linking subject access systems like LCSH and DDC. c. for providing navigation and retrieval tools based on outlines of knowledge within classification schedules. 2. Extend the use of library classification to Internet resources. 3. Improve presentation of information in library classification schedules, including more lead in vocabulary, more understandable scope notes, better captions, references, and indexes. 4. Share development strategies among and between various classification systems and thesauri, creating the ability to link with one another including multilingual and specialized systems. 5. Work with vendors of Online Catalogs so that these systems will include features where classification systems and thesauri can be used for file partitioning, navigation, and retrieval. 6. Build bridges from the past (e.g., library collections classified by DDC, LCC, etc.) to the future (e.g., digitized full text collections). 7. Educate consumers, administrators, and practitioners about the value of library classification systems beyond mere shelf arrangement. 8. Conduct more end-user research to determine utility of library classification systems new and improved. 9. Reach out to other professions for ideas, stimulation, collaboration, and convergence on the problem of organizing networked information. 10. Challenge the status quo in the realm of library and networked information systems and services. 11. Make the classification schemes more educational so that the user can be guided to see relationships and cognate information they might not otherwise have known. 12. Organize the classification schemes differently for the end-user than for the classifier and provide more than one scheme for users to browse and navigate before and after retrieval
