Abstracts fall into two different kinds; the informative and the indicative.
Informative abstracts follow the organization of the paper and address these key points.
Indicative abstracts do not always follow the structure of the paper and provide a content summary, either of the argument of the document or the contribution made to the understanding of the topic or the issue
During the research process, reading an Abstract can help you to determine whether a source is worth reading all the way through or not.
When you first begin doing research, you may get hundreds of thousands of search results, which can make the research process overwhelming. However, there are a number of ways you can refine and focus your searching to make your list of results more manageable.
Boolean operators (AND, OR, NOT) can help you to limit or expand your search.
Gil-Find, Galileo Discover, and many subscription databases enable you to refine your results beyond using boolean operators. In most interfaces, you will find a menu on the left hand side of the screen (like the one pictured here), which will allow you to make decisions on what to include or exclude from your search results. Limiting by subject and language can be particularly helpful.
Refining your search results using the limiters provided by a given database can help your search results to be more focused, and more manageable.
