Because of newly developed technologies and the escalating cost of printing, more organizations are delivering documentation through online mediums. This trend has serious implications for users of legacy documents (i.e., printed documentation). This paper reports the results of two studies that assessed customers' use of documentation. The studies found that printed documentation remains an important source of information and support for some usersthat despite an increased amount of documentation delivered in online mediums, printed documentation continues to be significantly valued and used by customers with particular learning strategies and by customers in retrieving certain types of information. The paper concludes by discussing implications for organizations whose products require documentation and for technical communicators who produce it.
