Winter 2020
The purpose of this guide is to provide students with instruction and resources to successfully complete the CHEM 142 Current Events Annotated Bibliography Assignment. After working through these guide pages students should be able to locate and identify scientific sources that are both credible and appropriate.

Additional Drop-In Workshops

Drop-In Help Sessions 

Your Chemistry instructors will provide you with a link to the drop-in schedule via a Canvas announcement.

Follow the instructions in the announcement to pick a day and time that suits your schedule for the library drop-in session.

Librarians are also available during most of the library's open hours to help with any of your CHEM 142 questions.

Types of Sources

For this assignment, you can use the following types of sources:

  • No more than one (1) web page. NOT Wikipedia!
  • No more than one (1) article from an encyclopedia, and then only if the article has relevant scientific information.
    • Find recommended encyclopedia databases in the "Recommended Databases" tab.
  • Articles from scientific journals, located using library databases or online search sites (such as
    • It is likely that you will find articles that are not available in full text. You may use the abstract for the initial 8 sources in this assignment. Use the "Find It" feature in library databases to have the full-text of an article emailed to you. For the final four sources you MUST have the full text of the article.
    • Scientific articles can be a challenge to read. See the tab called "How to Read a Scientific Article" for help.
  • Relevant, scientific books, including textbooks. Cannell Library has access to many up-to-date print books and ebooks. You can also borrow books from 38 other university and college libraries through the library catalog. See the "Introduction to Clark Libraries Catalog" tab.

Can I use this source?

The following periodicals are examples of good places to start for learning about your topic, and they may be one of your eight articles, but they should not be in your final four. Your final sources should be from more quality publications. 

  • Scientific American
  • Discover
  • Smithsonian
  • National Geographic
  • "journals of opinion" such as New Yorker and Atlantic

If in doubt, check with your instructor. 

Q & As about Sources

Question: If I find a document on a website, like a government document or a research paper, from a .gov or a .edu, that's in a separate pdf file, not the webpage itself, is it a document or a website?

Answer: For Chemistry 142, treat these are documents. They do not count as a website.
