In fact, Bliss is the only theorist who created an organizational scheme based on societal needs.
His solution was the concept of "alternative location," in which a particular subject could be put in more than one place, as long as the library made a specific choice and used it consistently.
Instead he used capital and lower-case letters, numerals, and every typographical symbol available on his extensive and somewhat eccentric typewriter.
Its first publication was the Abridged Bliss Classification (ABC), intended for school libraries.
Part of the reason for its success was that libraries in teachers’ colleges liked the way Bliss had organized the subject areas on teaching and education.
The Bliss Classification system has been found to be successful in academic, specialty, government, and law libraries.
