Types of Scientific Resources

Primary, secondary or tertiary sources depend on how close that information is to the source of the original lab research. In the sciences, research findings are communicated through conference proceedings, journal articles, technical reports, self publications, or edited volumes in a series on a certain topic. Secondary sources pull from primary sources, and tertiary sources pull from secondary sources. Use the chart below to help distinguish between different sources.

GIS Resources

Fogler Library has a GIS Resources guide that will help you access different types of GIS data. The guide also includes information about different types of GIS software and professional organizations for GIS users.

Data sources are listed by region or by topic. Regional data sources are separated into local Maine data, US data, and international data.
