Why Should We Make Reference to our Books and Laptop Computers?

Encyclopaedias, dictionaries and manuals have one thing in common - they are all reference books. Reference books are needed whenever we have to discover the answer to a problem, or to discover the accurate spelling or definition of a word or to find out how to work with or fix a piece of equipment. Naturally how helpful these certain sorts of reference books are may be different from person to person.
