While the encyclopedia does present information from a Catholic perspective, it often offers in-depth and accurate portrayals of historical and philosophical ideas, persons and events. Due to its [[public domain ]] status, content from the 1913 edition can be incorporated into any work, as long as an individual does not try to pass off articles or information from the encyclopedia as his or her own. Text from the ''Catholic Encyclopedia'' appears, sometimes in an edited form, in online reference works such as Wikipedia.
