Is Britannica a periodical?
Just so, what type of source is Britannica?
Depending on the scope of your research, encyclopedias can be referenced as primary sources. For example, the Encyclopedia Britannica, one of the most popular encyclopedias, was first published in 1768 and is considered a primary source for historians because of the significant value it gained over time.
In this way, is Encyclopaedia Britannica a reliable source?
It is very reliable. It's reputation has long been that it is probably the “most respected” of all of the general encyclopedias. (Now, that may not mean it is as up to date as the latest professional journals published in a field, of course.)
