6 Control-Access-Directional Control Access- Directional sources also known bibliographies. Bibliographies are compilations or systematically produced descriptive list of records. Record pertinent information about each item listed, including its author, title, edition, place of publication, publisher and date of publication. Bibliographic sources answer questions about books, magazines, newspapers, libraries and publishing. Slide 6

7 Control-Access-Directional 2 Why Bibliographies are called Control Access- Directional sources? Bibliographies serve as control device or checklist Bibliographies inventory what is produced daily or yearly They enable both compiler or producer of bibliography and user to feel that they have a control, through organization, of the steady flow of knowledge. Slide 7

8 Control-Access-Directional 3 Why Bibliographies are called Control Access- Directional sources Bibliographies also provide access. They are prepared through research (that is, identification, description and classification of information). Once the items are controlled, individual items are organized for easy access to facilitate intelligent work. Slide 8

9 Control-Access-Directional 4 Why Bibliographies are called Control Access- Directional sources Bibliographies are also referred to as Directional because they do not give definitive answers, but serve to direct users to sources of answers. Most Control-Access--Directional sources of reference works are available not only in print but also in electronic format. Slide 9

Most Control-Access--Directional sources of reference works are available not only in print but also in electronic format. Slide 10

Guide to Reference Books The library catalog or the catalogs of numerous libraries; bibliographical utilities. eg. Online Computer Library Centre (OCLC), Research Library Information Network (RLIN) General systematic enumerative bibliographies eg, The National Union Catalog. Indexes and abstracts - bibliographical aids eg, The Readers Guide to PeriodiĐal literature, The New York Times Index. Slide 11

Examples of sources types include Encyclopedias, Fact sources, Dictionaries, Biographical Sources, Geographical sources and Government Documents. Encyclopedias eg, Encyclopedia Britannica; Encyclopedias on CD-ROM and online eg, Encarta Fact sources Almanacs, Handbooks, Manuals and Directories. eg. World AlŵaŶaĐ, StatesŵaŶ s Year Book. Dictionaries eg. Weďster s Third New IŶterŶatioŶal Dictionary; Biographical Sources eg. Who s Who Slide 13

15 Conclusion Neat categorization not always distinct in an actual situation. A bibliography may be only source required if question is merely one of verification or of trying to complete a bibliographical citation. Conversely, bibliography at end of encyclopedia article or a statement in that article may direct patron to another source. Two main categories access and source serve to differentiate among the principal types of reference works. With the introduction of computers neat categorization no longer exist. Electronic databases eg Emerald, EBSCO has bibliographic and full text. Slide 15
