Electrical engineering is immense in scope. Everything from microelectronics to the heaviest high-tension transmission lines lies within the discipline. The electrical engineer can be classified as anything from a lab-coated researcher to a field-oriented technician.
Electrical engineering is a field with a great deal of research movement and a long history of data gathering, both of which are important components in the professional duties of the engineer. The information must be both specific and current.
The literature of electrical engineering is well controlled. There are excellent abstracts and indexes available. The one area that is not well covered is gray literature. This is not a problem specific to electrical engineering, however.
