Most people will have their first contact with an article by seeing just the abstract,usually on a computer screen with several other abstracts, as they are doing a literature serch through an electronic abstract-retrieval system.Readers frequently decide on the basis of the abstract whether to read the entire article; this is true whether the reader is at a computer or is thumbing through a journal.
The abstract needs to be dense with information but also readablc, well organized,brief,and self-contained.Also,embedding many key words in your abstract will enhance the user's ability to find it.
