  1. Find a minimum of six sources on your topic –      these should be your best sources so that means you will likely have      reviewed at least twice this many
  2. ONLY use MLA citation formatting and use it      consistently in the assignment
  3. Look for reliable, valid sources that discuss      research and use academic language
  4. As you write your annotated paragraph include      both a summary of the source AND an evaluation of the validity of the      source and its usefulness. Paragraphs should be in full sentences 70-200 words long. Length of the entry is often linked with      the length of the source.
    1. Summarize the content of the source – be       descriptive and specific
    2. Evaluate the accuracy and validity of the source
    3. Describe the usefulness of the source
  5. The format should list the citation, then the      appropriate paragraph annotation followed by the next citation and      annotation. All entries should be      typed and double spaced.

Brief Example:

Castro, P., Huber, M.E. 2005. Marine Biology. 5th ed. New York: McGraw Hill. 451p.

This college-level classroom text provides an overview of oceanography, marine organisms, marine ecology, and human relationships with the ocean. Microbes are described in detail in one chapter but are again discussed in the context of different marine ecosystems. Prokaryotes and eukaryotes are detailed with descriptions of their varied metabolic reactions. Relationships of microbes to other organisms through symbiosis are highlighted as well as concerns of humans through plankton and microbial blooms. The text also emphasizes how understudied marine microbes are due to research interests and the difficult of studying fragile organisms at sea. As a recent publication by qualified marine researchers and teachers, Castro and Huber, with extensive academic review, the information is current and valid. The source provides an excellent overview for the advanced beginner including glossary and appendices, but requires knowledge of basic biology and chemistry.

Identifying valid sources:

· Look for the author’s credentials. Are they a person who has a documented knowledge of what they’re researching? Who is paying them to write this?

· When was the source created? Could research since the time of publishing have changed the information included in your source? If so, look for more recent works that give you the same (or different) information.

· What type of source is this – peer-edited journal, website, book?

· The depth and level of detail offered in the source. It should be appropriate to your level of understanding but use relevant vocabulary and cite research to support its information.
