Reference sources, such as dictionaries, encyclopedias, atlases, etc. are more general in their coverage of information. These kinds of sources provide information that may cover a wide expanse of subjects, but each entry is typically fairly brief and easy to read/understand without special knowledge. Reference sources serve as a great starting point to provide an introduction to a topic and a foundation for research.
