Acronyms
Acronyms are written in all capital letters, typically. Usually, each letter in an acronym is the first letter of one of the words in the phrase the acronym spells. The best use of an acronym is when it expresses a clearly understood phrase or concept without having to spell out all of the words each time. Several rules of thumb can be followed to ensure acronyms are understood accurately. 1. Spell out the acronym before it is used the first time in a document 2. Understand who the target audience is 3. Understand what the knowledge base of the target audience is. When used correctly, an acronym is an example of Ranganathan's Fourth Law of Library Science--save the Time of the Reader.
