but this need only be in the author-entry. Upon these lines the book before us appears as

Anstey, F. (pseudonym of T. Anstey Guthrie),
and the reference reads
Guthrie, T. Anstey. See Anstey F. (pseud.)

There is the difficulty that occasionally arises of an author publishing under a pseudonym and under his real name and being equally as well-known under both. Instances of this would be the Rev. John M. Watson, whose theological works appear under his own name, and his stories under “Ian Maclaren;” and J. E. Muddock, who publishes some stories under that name and, it is said, his detective stories under the name of “Dick Donovan.” Common-sense might offer the suggestion to adhere to the rule already laid down and enter under both names, but this violates one of the first principles of dictionary cataloguing, viz., that all works by an author must be brought together under a single name. Therefore in such cases there is no option but to adopt the real name, at the same time taking care to remove all occasion of difficulty by giving cross-references, as
