PRINT MEDIA NOTES

  1. BIBLIOGRAPHIC SOURCES

This is an information sources that hold descriptive information about a work. This information includes the origin of the work (author, title, imprint etc). They also contain details of non – print media e.g. if it is a film it will contain the title, producer of the film, date it was released and its duration. A bibliographic source links the information seeker to the source of information. A bibliography facilitates access to published documents to the users.

Indexes

An index is a systematic list of concepts, terms that describe a collections or a document. It also a tool guiding the inquirer to the document. An index is a product of indexing. Indexing is the process of analyzing information or subject knowledge of reported knowledge and expressing the information in the language of the indexing system. Indexing involves scanning through a collection/documentation analyzing its contents then selecting the concepts to be indexed and eventually, the item/concepts provided with a precise location e.g. page number, chapter etc.

An index will generally contain a table of contents, places or persons mention in a collection.

FUNCTIONS OF AN INDEX

  • It’s a guide to specific terms in a collection hence helps searcher locate items effectively and may also be used to browse among related entries.
  • It helps to bring the language of the index and that of the user together. The main purpose is to provide a means of locating a particular type of information when needed therefore minimizes search efforts.

PREPARATION OF AN INDEX

  • Requires accumulation of entries into a cohesive and consistent form.
  • Establish identifiers, which are effective.
  • Determine the physical form in which the index is to be published (e.g. manual or computerized) and made available to the public.

TYPES OF INDEX

  • Author index: Gives the name of author first (surname) followed by his works (title, location in the collection). An author catalogue can be identified as an author index.
  • Title index: Gives the title of the work.
  • Subject Index: Gives the subject of a work.
  • Concordances: Mostly used in a bible. It guides searchers to the words used in a document, it form is derived in the title of a document on the whole text.
  • Citation Index: This provides a list locating earlier reference or more recent work.

Abstract

It is a summary of a large work. Its defined a fewer words yet retaining some sense. It is a condensed form whereby details are omitted but still retaining the original work.

USES OF ABSTRACTS

  • Are important in the field of translation as they enable an information seeker to still get hold of the information. It is translated into a language understood hence overcoming language barrier between information sources and seeker.
  • Abstracting services facilitate selection of documents by the user’s and information personnel because it provides essential points about the work.
  • In most educational books the nature of the work is contained in the publisher catalogue, purpose of the work, which can enable an individual to consider whether or not to choose the item for the collection.
  • They act as an aid to the reader or selector in accessing the content of a document and its relevance.
  • It substitutes an original document and due to its brevity less time is used to digest information and hence higher retention.
  • They are less expensive than the original documents.
  • It’s a tool for literature search and here searching for information is accompanied by the use of an index so as to be able to through a vast collection of published works.
  • It facilitates indexing through scanning through an abstract and choosing the concepts and terms to be used in an index.
  • They are used in the provision of current awareness services (CAS), which alerts users about up to date information of their area of interest.
  • They facilitate literature review – this is searching for information either in a research topic or assignment.

QUALITIES OF A GOOD ABSTRACT

  • It must be concise i.e. stick to the point and care should be taken to ensure that long phrases are replaced by single words.
  • Precision meaning only the expression that is exact and specific should be used especially when summarizing the original document.
  • Self – sufficiency – The document should be complete, accurate and easily understandable hence an abstract must be fully informative.

  1. Title only abstracts

This type of abstract describes the documents without elaboration about subject content.

2. ENCYCLOPEDIAS

There are 2 types of encyclopedias

General

Subject (specific)

It’s a book giving information on all branches of knowledge or specific subject. Also known as storehouse of knowledge.

It is a source commonly used as a reference tool. They are useful in solving research problems because they answer questions like what, where, when, how an event occurred. They can be general i.e. covering wider variety of a subject encyclopedia, which explores a particular discipline.

Examples

Encyclopedia – Americana

McGraw Hill Encyclopedia of science and technology.

Learning Activity

Pick a general and subject encyclopedia from the library and highlight the following

  1. The type of information found in the two types of encyclopedias.
  2. State the difference between the subject and general encyclopedia.

 

  1. DICTIONARIES

It contains the words of a language, terms of subject or professions arranged in a definite order.

Usually an alphabetical one. It gives meanings, spelling, pronunciation, uses/applications and origin – etymology.

It can also be general e.g. oxford dictionary and also specific e.g. law dictionary. Gives terms in legal profession. It is therefore a compilation of words in a language arranged in alphabetical order and defined in the same language. It is also a compilation of words in a language translated into one or more language.

Electronic dictionaries mainly used in computers

Glossary: A glossary is a kind of dictionary that translates technical terms of a language/discipline used in a field or in a document into a more easy to understand words of the same language. E.g. Harold’s librarian glossary.

Thesaurus dictionary: Consist of a set of controlled terms linked by hierarchical or associative meaning or relationship. E.g. thesaurus of engineering terms.

 

  1. ANNUALS

Almanac

According to ALA glossary an almanac is an annual publication containing a calendar frequently accompanied by astronomical data and other information.

  3. Trade directory
  4. Postal or fax directory

Highlight the type of information found in each source

  1. GEOGRAPHICAL SOURCES

This is a source of information that has the ability to transport the viewer of information seeker to any part of the world/universe.

These are primary graphic presentation, which allow the user to have full information of a given region/locality. Most of these sources are words and provides a type of satisfaction rarely found in purely textual approach to knowledge.

Types include atlases, maps, gazetteers, and globes. These sources are normally very accurate.

HAND BOOKS AND MANUALS

Hand books are also important reference sources and play a very big role to a library and information services. It is a compilation of miscellaneous information in a compact handy form. They act as tools that enable users to get information needed first and promptly.

A manual is also a current reference source, which can be defined as an instruction in book instructing on how to do something by means of specific and clear direction.

 

  1. SERIALS

In most cases the book reviews are usually found in books which the periodical falls.
  • Some periodical are published continuously over long period of times it s therefore possible to trace through them the development of give subject.
  • It serves as vehicles of permanent records or research finding.
  • They facilitate an exchange of information between author of the research finding and reader because they contain up- to- date information
  • Periodical are popular with users therefore justifies the purchase centre in acquiring them.
  • Most periodical are usually bought or purchased by subscription either directly from publisher or outer coutries can be expensive but nevertheless its beneficial venture.

Factor to consider in acquisition of periodicals

The information centers, standards have been used as a measure of guiding, establishment of new systems thus helping in checking uniformity. E.g.  The standards of cataloguing, indexing, classification and other practices. Bodies involved in ensuring uniformity in services in information sector e.g. IFLA, KLA, and FID.
