IN the Crimson of January 11 there appeared an article entitled "An Index to the North American Review." The article was mainly a compilation of facts from the Index lately completed by Mr. Cushing of the Harvard Library, and cost the author some time and trouble. In the Literary World of March 1 we find an article, "The Index to the North American Review," about which we wish to say a few words. We are always glad that the merits of the Crimson should be duly appreciated, and we cannot help feeling grateful to the gentleman whose name appears at the end of the article for his flattering though somewhat peculiar tribute. He seems to have borrowed his facts from the Crimson, not merely without the least acknowledgment of indebtedness, but under his own signature. Not that his article does not bear some marks of originality; he has one or two additional facts, and his language differs considerably from the language in the Crimson. This matter needs no further comment. The Literary World would have saved itself from this mistake if it had placed the Crimson on its exchange-list.
