HC 317: Bacterial Symbiosis: Tertiary Sources

Molecular Ecologist is a blog sponsored by the journal Molecular Ecology (Wiley).  Its purpose is to cover research and news in the field of molecular ecology.  The content is contributed by students and scientists.

Small Things Considered is a blog sponsored by the American Society for Microbiology (ASM).  Its purpose is to share appreciation for microbial activities by selecting items from the current literature that are unusual and exciting.  The content is contributed by students and scientists.

Tertiary Sources

Both secondary and tertiary sources are second hand accounts (versus primary sources which are first hand accounts) in that they convey the findings, experiences, and opinions of others.  Tertiary sources are further removed from the original information than secondary sources.  Determining if a source is secondary (summarizes research) or tertiary (summarizes knowledge) can sometimes be tricky.

Tertiary sources may be used to:

  1. Learn about the topic (get basic background information)
  2. Identify keywords to use when searching the literature (develop search strategy for databases)
  3. Provide starting point for accessing the literature (find secondary and primary sources listed as references)
