Technical reports are often prepared for sponsors of research projects. Another case where a technical report may be produced is when more information is produced for an academic paper than is acceptable or feasible to publish in a peer-reviewed publication; examples of this include in-depth experimental details, additional results, or the architecture of a computer model. Researchers may also publish work in early form as a technical report to establish novelty, without having to wait for the often long production schedules of academic journals. Technical reports are considered "non-archival" publications, and so are free to be published elsewhere in peer-reviewed venues with or without modification. A technical report is a formal report designed to convey technical information in a clear and easily accessible format. It is divided into sections which allow different readers to access different levels of information. This book explains the commonly accepted format for a technical report; explains the purposes of the individual sections; and gives hints on how to go about drafting and refining a report in order to produce an accurate, professional document.
