Below are outlined some of the more obvious one. Save on the cost of paper. At a time when the cost of paper is rising dramatically, publishing without paper can be very cost effective. Company materials are distributed, and if the customer wishes to see a hard copy, it is up to them to provide the paper. An increasing number of technical and user manuals are being distributed this way.
Mass production is relatively inexpensive.
Most of the cost of producing an electronically published piece is incurred when getting the material ready. But after the master is completed, mass production is extremely cost effective when compared with conventional publishing. Revisions are cheaper. Just insert the changes and get the new master produced. If a company has a web site, revisions can be done with little or no extra cost.
