 Since its reorganization, the "Macropædia" has not remained constant.New articles are constantly being added, whereas older articles are sometimes split, absorbed into other articles or drastically shortened, even deleted.An example of the latter is the 1989 article on Adhesives, which had its own article of 7 pages in the 1989 "Macropædia" but was merely a page in a different article of the 1991 edition.
