The history of word square construction in the United States has largely been one of the strenuous attempts to build the largest possible word squares. While size of a legitimate objective in logological pursuits, word square experts such as the formists of the Eastern Puzzlers' League and the National Puzzlers' League permitted that objective to dominate them completely. As a result, they sacrificed word square quality: most of their constructions were of unacceptably low quality. More recently, word lists have been fed into computers programmed to construct all word squares extractable from words in the lists used.
