Good Documents
1998

Abstract:

While parts of a document should be concise, provide detail whenever it may help the reader. Computer documents often have less total space constraints than paper documents, so the cost of providing extra details may be small. In fact, sometimes providing details can cut the cost of writing the document by saving time from writing summaries.
