Using the Web

It is important to evaluate the websites you use for your reserach. There is some very authoritative information available on the web, and there is less reliable information. To evaluate sites, consider these criteria:

Purpose: What is the purpose of the site? To inform? To persuade?

Authority: Who is the author of the webiste and what are the credentials of that person or entity? The author may be an individual or an organization.

Timeliness: How current is the information? Can yo utell when it has been undated last?

Scope: How deep is the website? Is it within your range of comprehension? Is it too simple? Is it too technical?

Using The Web For Research

PATS: Acronym for Evaluation indicators
Purpose Is the intent to INFORM or PERSUADE?
Authority Scholar? Journalist? Experienced in the topic? Whatever it is, what does it mean in the context of history? Of a country? Of a time period?
Timeliness Depends on your topic whether currency is important
Scope Do you want something that covers the topic broadly, specifically, or in-depth? (e.g., respectively, encyclopedias, news or scholarly articles, and books)

Websites

The following web sites are helpful in locating information about chemical compounds, molecules and elements.

More Websites

American Chemical Society Publications. Search of the publications of the ACS; limited full-text but a wealth of citations.

Energy Citations Database. Access to citations and full-text articles from 1943-present in an array of science fields.

NASA. National Aeronautucs and Space Administration.

PubChem: provides information on the biological activities of small molecules. It is a component of NIH's Molecular Libraries Roadmap Initiative. PubChem is organized as three linked databases within the NCBI's Entrez information retrieval system. These are PubChem Substance, PubChem Compound, and PubChem BioAssay. PubChem also provides a fast chemical structure similarity search tool.  

Science.gov. Gateway to a large selection of websites, narrowed by topic.

Science Research:  A free, publicly available deep web search engine that uses advanced "federated search technology" to return high quality results by submitting your search query - in real-time - to other well respected search engines then collating, ranking and dropping duplicates of the results.

Science Watch. Allows you to follow current trends and research in chemistry.

World Wide Science. Gateway to national and international scientific databases.
