The online version of the "Encyclopedia Americana", first introduced in 1997, continues to be updated and sold. This work, like the print set from which it is derived, is designed for high school and first-year college students along with public library users. It is available to libraries as one of the options in the Grolier Online reference service, which also includes the "Grolier Multimedia Encyclopedia", intended for middle and high school students, and "The New Book of Knowledge", an encyclopedia for elementary and middle school students. Grolier Online is not available to individual subscribers.
