CLASSIFICATION What is Classification Grouping of items Making

CLASSIFICATION

What is Classification • Grouping of items • Making subgroups • Arranging the groups, and the items within the groups

How can we classify books? • • • Size Colour of cover ? ? Subject

Why do we arrange books by subject? • To make it easy to find the information that a reader is looking for. • Classification brings together all books on the same subject, so all similar information is brought together

Why do we not arrange books on shelves according to author or title or year of publication or serial number? • Because that would not be useful for finding information

In Book Classification • We group the books according to the subjects, and arrange them on the shelves.

How will we group these books? • Take the list of books provided and suggest how you will group them in a library

Why Classification? • To organise Collection – Like subjects together – Separate unlike • To Retrieve Collection quickly • To manage Collection efficiently ( adding, withdrawal, stock checking, etc. ) • For future, situations like shift of location, merging library with other library.

Subjects • • Science Applied sciences and Technology Social Sciences History, Geography Language and Literature Philosophy, religion Arts- Fine & decorative, performing Sports and games

Now we have made the arrangement • If a person borrows a book, and returns it after a few days, how will we know where to put it back? • So we have a notation

Notation • Notation is a number or alphabets or symbols, which represents the subject of the book, E. g. 370 - Education • The notation has a built-in order of arrangement e. g. 350, 360, 371, 372, … 380… • So the notation shows where the book is kept on the shelf

A Classification Scheme • A classification scheme is a list of all subjects, arranged in groups • For each subject, a symbol/number is given, i. e. the notation

Popular Schemes Used • Books are classified using tools for book classification such as : – Dewey Decimal Classification – Library of Congress Classification – Universal Decimal Classification – Colon Classification, etc.

The Dewey Decimal Classification Scheme • Most popular book classification scheme in the world • Simple to understand • Makes it easy for users to find books • Regularly revised to add new subjects

Organization of DDC • Four Volumes – Vol. 1 – Vol. 2 – Vol. 3 – Vol. 4 Introduction and Tables 000 -500 Class 600 -900 Class Relative Index and Manual – 19 th edition is in 3 volumes only

The Dewey Decimal Classification Scheme All subjects are divided into 10 main classes: • 000 Computer science, information & general works 100 Philosophy & psychology 200 Religion 300 Social sciences 400 Language 500 Science 600 Technology 700 Arts & Recreation 800 Literature 900 History & Geography

Another example • 300 Social sciences, sociology & anthropology 310 Statistics 320 Political science 330 Economics 340 Law 350 Public administration & military science 360 Social problems & social services 370 Education 380 Commerce, communications & transportation 390 Customs, etiquette & folklore • 370 Education 371 School management; special education • 372 Elementary education • 373 Secondary education • 374 Adult education • 375 Curriculums • 376 No longer used—formerly Education of women • 377 No longer used—formerly Ethical education • 378 Higher education • 379 Government regulation, control, support

Dewey Numbers • Each number indicates the bigger classes to which the subject belongs • E. g. 500 – Science 540 – Chemistry 546 - Inorganic Chemistry 546. 652 – Chemistry of Copper and its compounds

Decimal arrangement Arrange the following numbers: • 628. 9 • 628. 1401 • 628. 25 • 625. 82 • 625. 0115

How do you decide what is the subject of a book? • 1. See the title. But that is not enough. E. g. Animal Farm is not about Zoology or agriculture • 2. Look at the preface and contents • 3. If necessary look at the chapters

How to classify books using DDC • 1. Look carefully at the book and decide its subject • 2. Decide the subject group in which you will put the book. • 3. Select the most specific number for the subject of the book e. g. if the books is about monkeys, do not put it under Zoology, or mammals; look for the specific number for monkeys • 4. If necessary, use the index to the DDC

Where you will classify these…. • • Butterfly Indian politics Ramayan in Marathi “Shivaji the Great” “Wings of Fire” Calligraphy Water Dowry Prohibition

• • • Temples of India Marathi Dictionary Electricity ‘I Dare’ : Biography of Kiran Bedi Export of Rice Cooking Rain water harvesting Poems on Rain

Adding Tables • DDC 21 st ed. has 7 tables • Table 1 is Standard Subdivision Table which is common for all classes, can be used throughout the schedule. • Table 2 to Table 7 are special table and should be used only when instructed in the schedule.

Adding Standard Subdivisions • 03 Dictionaries and Encyclopedia • 05 Journals and magazines • 07 Education and Research – 071 Education, study and teaching – 072 Research • 09 History of a subject, Person

Use of Summary given at individual Class • Dictionary of Library Science 020. 1 -. 9 std. subdiv. Therefore, Final number will be 020. 3 • Dictionary of Higher Education 378. 001 -. 009 std. subdiv. Therefore Final number will be 378. 003

How the books are shelved left-to-right, top-tobottom That means you start at the left on the top shelf and move to the right until the shelf ends.
