Carl Linnaeus is most famous as the father of modern taxonomy. What's not so well known is that in his effort to manage vast amounts of data, he came up with a revolutionary invention: the index card.

Difference between index and Abstract:

Index Abstract

An index consist of short indention of information with adequate bibliographical citation.

Whereas an abstract consists of concise representation of an original document with adequate bibliographic details

Index help to locate the required information.

Abstract helps to locate as well as select the required item.

Index is only used for fact finding.

Abstract is also used for searching document and at the same time it also insists the user to read the real document.

An index is usually indicative.On the other hand abstract plays role as not only indicative but to informative.

An Index is not a real surrogate of the document

Whereas informative abstract can be claimed so.

Why we use index:

1. save time and effort in finding information.

2. identify potentially relevant information.

3. Indicate relationship among term.

4. Group together related topics.

5. suggest related topics.

6. tool for current awareness service.

Why we use Abstract:

1. it alert's the user newly published work .

2. it helps in keeping up-to- date with new knowledge.

3. It help to researcher to save time .

4. Informative abstract ,sometime can serve as a subtitle to the original document.

5. An abstract service might be called as the encyclopedic function.

6. It aids in the writing or reviews.

7. it help in improving index.

Barriers to use:

Coasts

Seats limitation

Information literacy instruction-Survival

Conclusion:

it is difficult to know what new has been published even in a small area of specialization as literature is being published at a very fast alarming rate. These service s have been found to be very helpful in deciding which article is to access and use which are not.
