Why Encyclopedias Got Bigger . . . and Smaller

This article will show that the European encyclopedia's critical period of growth took place from 1690 to 1840; the size of the largest printed encyclopedias declined or stabilized thereafter. Having established this pattern of change and its importance for encyclopedism, the article will then evaluate the factors determining the change. The early growth of encyclopedias was above all a consequence of competition, perceptions of the market for encyclopedias, and publishers' and contributors' psychology, while the most important causes for encyclopedias' lack of growth after 1840 were the standardization of encyclopedias as products, the cost of compilation, and financial conservatism among encyclopedia-makers.
