Jack London was accused of plagiarizing

In 1907, an article in The Independent suggested that London had plagiarized Egerton R. Young`s book My Dogs in Northland.
The article placed passengers of both books side by side so the reader could compare. In an accompanying letter, London admits using Young`s book as a source for the novel, and had even told Young that himself. But because Young`s story was nonfiction, and since London did not use the same language, he did not consider it to have been plagiarism.
