The article gives a general introduction to the form and function of t
he TEI header, points out some of the reasoning of the Text Documentat
ion Committee that went into its design, and discusses some of its lim
itations. The TEI header's major strength is that it gives encoders th
e ability to document the electronic text itself, its source, its enco
ding principles, revisions, and characteristics of the text in an inte
rchange format. Its bibliographical descriptions can be loaded into st
andard remote bibliographic databases, which should make electronic te
xts as easy to find for researchers as texts in other media, including
print. Its major weakness is that it does not yet provide the ability
for retrieval across texts in a networked environment, which users ma
y want now or in the future.
