Answer:
An encyclopedia is a better source for background information.
Step-by-step explanation:
The most important background sources are encyclopedias and dictionaries. Class textbooks also provide background information. These are considered tertiary sources
An encyclopedia is a reference work . General encyclopedias may contain guides on how to do a variety of things.
periodical is meant to be issued at regular intervals, and each issue has wholly new content. ... Therefore an encyclopedia is not a periodical.
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”.
