Journal articles, title purpose

Read and review the titles and abstracts of the journal articles that you collected during your literature search (started in chapter 2). How well do they capture the purpose, principal results, and conclusions of the work ... 

Browse through the Table of Contents of several Issues of Analytical Chemistry or Environmental Science Technology. In most issues, you will see that, in addition to research articles, the journal also contains news articles, editorials, features, and/or book reviews. Glance through the pages of two such items. For each item, jot down its title and the name of the journal section in which it appears identify the intended audience and purpose of the entry. 

The major purpose of the title is to inform readers about the specific content of the work, ideally identifying both what was studied and how it was studied. The major purpose of an abstract is to summarize, in one clear and concise paragraph, the purpose, experimental approach, principal results, and major conclusions of the work. In most journals, the abstract includes only text in some journals (e.g.. The Journal of Organic Chemistry and Organic Letters), the abstract also includes a graphic. Importantly, both the abstract and title must be able to stand on their own. This is because these two sections (and only these two sections) are reprinted by abstracting services (e.g.. Chemical Abstracts Service, or CAS) in separate documents for literature searches. Also, many chemists read titles and abstracts to obtain a quick overview of the journal s contents but do not read the articles in full.
