The set was originally published in 1921–1924 as the New Gresham Encyclopedia in 12 volumes, by the Gresham Publishing Company of London. Its editors were Angelo Solomon Rappaport, Richard Ferrer Patterson and John Dougall. An abridged 6 volume edition was published in 1927 as the Compact Encyclopedia by the same company and the latter two editors. It contained about half the material as the original edition.In 1933 it was published again, but now by Collins Publishers, of London. This edition was in 10 volumes and edited by John Maxi Parish. It was also republished the same year as The British Encyclopedia by Odhams Press. The content consisted of brief, unsigned articles and the encyclopedia was considered mediocre in quality.From 1933 to 1976 it was published in the United Kingdom as Collins Concise Encyclopedia, apparently as a work "of no great reputation", according to Kenneth Kister. In 1979 an abridged 2 volume pocket sized (8 by 12 cm, 3.25 by 4.75 in) edition was published as Collins Gem Encyclopedia. It was distributed in the United States by Simon and Schuster. A revised edition was published in 1980. the set had 1,125 pages, 450,000 words, and 14,000 articles. The articles averaged 32 words each, about 12 or 13 per page and were all unsigned. There were 5,000 cross references, but no index. There were no maps or illustrations, either. An editorial staff of five was listed. The subject coverage was broad, but superficial. For instance, Pearl Harbor only had a parenthetical note in the article on Hawaii mentioning that it was attacked by the Japanese during World War, bringing the US into the Second World War. Controversial subjects such as abortion and Scientology were handled superficially, the former simply had a 40 were medical definition and the latter adding the "controversial practices have led to official inquiries in some countries", and nothing else about the controversies surrounding the group. Like all entries in the Collins GEM series, it had a flexible, vinyl cover. The set went out of print in the US and Canada in 1987.
