Writings on design
Gloag's A Short Dictionary of Furniture (1969) was a reference book covering the history and types of furniture from the tenth century to the 1960s.
Gloag's first science fiction novel, Tomorrow's Yesterday, (1932) was inspired by the work of H.G. Wells and Gloag's friend Olaf Stapledon.  Tomorrow's Yesterday is a satire that depicts a race of cat people from the distant future observing human society.  In The New Pleasure (1933) a powder that greatly increases the sense of smell causes a social upheaval. Winter's Youth (1934) revolves around a longevity technology, which falls into the hands of a corrupt politician, with disastrous social consequences. In Manna (1940) a journalist discovers a plan to develop a fungus that could end world hunger. 99% (1944) is about an experiment to give humans access to their race memory.
