2 What is it? Subject analysis Examination of a bibliographic item by a trained subject specialist to determine the most specific subject heading(s) or descriptor(s) that fully describe its content, to serve in the bibliographic record as access points in a subject search of a library catalog, index, abstracting service, or bibliographic database. When no applicable subject heading can be found in the existing headings list or thesaurus of indexing terms, a new one must be created.

4 Why do all that? If we don’t we can’t find stuff! “Subject analysis is defined broadly as all methods and processes which can be described as representation for retrieval of information by its subjects, be they names, geographic locations, or topical subjects.” Quoted from Williamson, N. J. (1997). The Importance of Subject Analysis in Library and Information Science Education.

5 The rose by another name Intellectual access Mission and Goals of the School Library Media Program The mission of the library media program is to ensure that students and staff are effective users of ideas and information. This mission is accomplished: • by providing intellectual and physical access to materials in all formats • Information Power: Guidelines for School Library Media Programs (1988), p.1
6 What’s that all about? What’s the difference betweenintellectual and physical access???What is it all about?It’s about what it’s about, compared to touching on the book Now, figure that one out! Librarians talk about ABOUTNESS
7 Aboutness Aboutness The totality of subjects explicitly or implicitly addressed in the text of a document, including but not limited to the meaning(s) of the title, the stated and unstated intentions of the author, and the ways in which the information may be used by readers. Levels of specificity must be considered in ascertaining the subject(s) of a work.
8 What do you mean?Example from aboutness entry in ODLIS: In the case of the hypothetical title The Japanese Teamwork Approach to Improving High School Effectiveness, is the work about: 1. education? 2. educational effectiveness? 3. high school effectiveness? 4. teamwork? 5. a Japanese approach to teamwork? • What do you say? See next slide!
9 What’s the rule? Choose the most specific heading As a general rule, catalogers and indexers assign the most specific subject headings that describe the significant content of the item. [In] the Library of Congress Subject Headings list, the appropriate headings might be “High schools-- Japan,” “Teacher effectiveness--Japan,” and “Teaching teams--Japan.” • Aboutness entry in ODLIS
10How do you find out?Walk like an Egyptian? • NO! Think like a librarian!!!!
11Yeah, Think Like a Librarian!
12An Important Factor Cataloger’s judgment Individual perspective – Informed by the cataloger’s background knowledge of the subject – Informed by the cataloger’s cultural background Consistency in determining “What is it about?” leads to greater consistency in assignment of subject headings • Basic Subject Cataloging Using LCSH —Trainers’ Notes
13 Another perspective It’s ―a precarious business‖ The ability to determine what the item is “about” depends a great deal upon the cataloguer’s knowledge, biases, and judgment. Deciding the “aboutness” of a particular item also relies upon the patrons, which are served by a particular library or library system. Library Sciences Site Paula Laurita Guest Author
14In other words How you do it Depends on 1. What you know 2. What your users know (or, rather what you think they know!) 3. What you think might interest your users
15 Steps1. Determine the main subject or subjects of the book This is done by examining the title, table of contents, description on the dust jacket, preface, text, and illustrations.2. The next step is to write down the subject and check to see if that choice is permitted in the standardized list. If the subject selected is not in the list, the related subjects must be consulted. It is possible, although not advisable, to add a local subject heading. • Chapter 6: Subject Headings
16 Why use a standardized list?Why Subject Headings? Subject headings often indicate the contents of books in terms that their titles do not use, which often may be nondescriptive or very general. Subject headings in online databases are often referred to as descriptors, but they serve the same purpose in locating valuable resources. Along with their subdivisions, subject headings provide a clear and systematic way of scanning the catalog for what is needed. Assigned headings are usually the dominant, and most important, subjects of a given item. Subject headings bring like materials together, requiring less use of the wide variation of synonymous terms that may appear to describe a single concept (teen, youth, adolescent, young adult, etc.). • Using Subject Headings in PantherCat
17 Robert Bratton, original cataloger, discusses thequestion ―Where do subject headings come from?‖ (a) The stork delivers them. (b) They grow on trees. (c) They magically appear on catalog records (which also magically appear). (d) Through the determined, diligent work of librarians. As a cataloger, I wish the answer was a, b, or c, but I know too well that it is d. No longer publicly available on the web
18More on subject headings Bratton explains: First, catalogers at the University of Maryland Libraries utilize Library of Congress Subject Headings (LCSH) on bibliographic records. Second, LCSH is based upon the concept of “literary warrant,” which means that the topics in published literature drive the creation of subject headings. New subject headings are created when works about new topics are published and acquired by libraries. When a cataloger cannot find an appropriate subject heading for a work, he or she then considers proposing a new subject heading. Where do subject headings come from? From
19 What about LMS and subject headings? Manitoba provides an answer that is true forUSA as well: The individual library may choose between Sears List of Subject Headings and Library of Congress Subject Headings (see Bibliography). The Sears List has long been the standard for school and smaller libraries. For most school libraries it will suffice. The Library of Congress subject headings should be considered only for larger libraries. All other situations cannot support the cost. Changes in technology may justify the use of Library of Congress subject headings in the future. Commercial vendors will provide the opportunity to select one or the other or both. When cataloguing is purchased, both Sears and Library of Congress subject headings should be requested. Then when the records are loaded, Sears would be used for the present time. The school library must update its edition of Sears regularly.
21 Tips on using SearsUse as specific a heading as possible: A book about bears should be given the subject heading BEARS rather than the general heading ANIMALS. For a book about several different animals, the more inclusive heading ANIMALS should be used rather than separate headings for each animal mentioned in the text. Determining whether to use a specific or a general subject entry can pose difficulties. The introduction to Sears describes how to designate them correctly. School libraries often find it valuable to include subject headings for Fiction and Easy materials. This makes it easier to identify storybooks about a particular subject or theme. In general, add the word FICTION as a subdivision of other subjects to indicate that the item is a work of fiction. From Cataloguing and Processing ch. 6
