Tertiary sources consist of information which is a distillation and collection of primary and secondary sources
- Handbooks - a type of reference work, or other collection of instructions, that is intended to provide ready reference. Handbooks may deal with any topic, and are generally compendiums of information in a particular field or about a particular technique. They are designed to be easily consulted and provide quick answers in a certain area.
- Subject Specific Encyclopedias - are especially useful when you need to become familiar with aspects of a discipline. Paging through a subject-specific encyclopedia can help you discover or focus a topic for a research paper or project. These sources are written by authors with specialized knowledge of the discipline.
