Information Types in Chemistry

How Can You Tell the Difference Between Types of Periodicals?

Cover Scientific American Canadian Chemical News Scholarly Journal: Journal of Research & Developments in Chemistry
 
Magazine
Trade Journal
Scholarly Journal
Author
Most articles are signed, though  not all. Authors are a mix of science journalists with a few academics from different fields A mix of writers for the publications and academics in chemistry Primarily academic researchers and scholars in the field of chemistry
Content 
Articles are accessible and do not assume prior knowledge. News briefs, opinion, letters, professional development, research briefs or overviews. Assume some knowledge Original research, literature reviews of existing research, & analysis. Use specialized terminology and assume knowledge in the field
Research
Authors speak to researchers, cite some experts. No references. Collection of original research briefs, interviews, news. Research briefs will have reference. Primary research or metareviews and analysis of existing research. Original work. Extensively cited
Editing
Edited by a general magazine editor. Edited by publication editor Peer reviewed for publication by specialists in the field
Audience
Written for the interested general public Written for professionals working in a field Working for other researchers and scholars
Purpose
To inform and entertain To support and inform those working in a field  To further knowledge in the subject area

One way to check if a journal is a peer-reviewed scholarly publication: check the journal website for their editorial policy.

One word of warning: Scholarly journals may contain book reviews, news briefs, and editorials. Checking the scholar peer-reviewed journal box in a database is step 1 to finding scholarship. You still need to assess the article itself.

Scholarly Literature

What is Scholarly literature?

Scholarly literature refers to journals and books of original research and analysis that further our knowledge in a field.

Scholarship is how academics and researchers stay current in their fields.

Scholarship is a conversation in which authors look for gaps in existing research and knowledge, and they build on, test, reinforce, and/ or refute existing scholarship on their topic.

Types of Scholarly Articles

Three types of scholarly articles in chemistry:

A Research article reports on an original experiment or study that investigates a stated problem. The study is carefully controlled so that results are valid. Data is collected and analyzed. 

Literature Reviews & Metareviews summarize and analyze the important articles on a topic. Literature reviews are a great resource for learning about the scope of research, questions, issues and theories in a field. 

A Theoretical article is an article that presents a theoretical approach to a question or field. It draws on others' research to support the theory, rather than presenting new research and data.
