Books. Books will often give you a greater amount and more in-depth information on a topic than encyclopedias and websites. They are a reliable source of information, having been written by authors selected for their expertise by publishers.

Encyclopedias are considered a scholarly source. The content is written by an academic for an academic audience. While entries are reviewed by an editorial board, they are not “peer-reviewed”.

Encyclopedias are highly recommended as a starting point for your research on a particular topic. Encyclopedias will give you introductory information to help you broaden or narrow your topic, while also providing keywords and terms needed to conduct further research.

Information can come from virtually anywhere — media, blogs, personal experiences, books, journal and magazine articles, expert opinions, encyclopedias, and web pages — and the type of information you need will change depending on the question you are trying to answer.

This guide will introduce students to three types of resources or sources of information: primary, secondary, and tertiary.

There are two kinds of sources: primary and secondary.

Three Sources of Research Problems

• Knowledge gaps.
• Omitted groups.
• Conflicting findings.

These are the different types of water sources around the globe and how they each play a role in what comes out of your home’s sink.

• Surface Water Resources.
• Groundwater Resources.
• Stormwater Resources.
• Wastewater Resources.
• Saltwater Resources.
• Ice Cap Water Resources.

Primary and secondary source examples

Examples of secondary sources include:

• journal articles that comment on or analyse research.
• textbooks.
• dictionaries and encyclopaedias.
• books that interpret, analyse.
• political commentary.
• biographies.
• dissertations.
• newspaper editorial/opinion pieces.

Primary sources can be described as those sources that are closest to the origin of the information. They contain raw information and thus, must be interpreted by researchers. Secondary sources are closely related to primary sources and often interpret them.

Secondary sources may have pictures, quotes or graphics of primary sources in them. Some types of seconday sources include: PUBLICATIONS: Textbooks, magazine articles, histories, criticisms, commentaries, encyclopedias.

For example, textbooks and reference books are tertiary sources.

The sequence continues with quaternary, quinary, senary, septenary, octonary, nonary, and denary, although most of these terms are rarely used.

Primary carbons, are carbons attached to one other carbon. (Hydrogens – although usually 3 in number in this case – are ignored in this terminology, as we shall see). Secondary carbons are attached to two other carbons. Tertiary carbons are attached to three other carbons.

Examples of tertiary sources include:

• Encyclopedias.
• Dictionaries.
• Textbooks.
• Almanacs.
• Bibliographies.
• Chronologies.
• Handbooks.

Examples of tertiary sources include:

• textbooks (sometimes considered as secondary sources)
• dictionaries and encyclopedias.
• manuals, guidebooks, directories, almanacs.
• indexes and bibliographies.

In addition, information technology, financial services, retail and foodservice have all become key aspects of the tertiary industrial sector.
