Sales Glossary, Sales Dictionary or Sales Encyclopedia?

Wondering what the difference is between the terms sales glossary, sales dictionary and sales encyclopedia? They are all related terms, best differentiated by their scope of content.

A sales encyclopedia is the broadest category. One definition for encyclopedia is “a literary work giving information on all branches or knowledge or of one subject, usually arranged alphabetically”. In years past encyclopedia sets were sold by door-to-door salespeople. A well known on-line encyclopedia is Wikipedia.com.

A sales dictionary is narrower in focus. A definition for dictionary is “a book explaining, usually in alphabetical order, the words of a language or words and topics of some special subject, author, etc.” Many of will remember referring to a dictionary in school.

A sales glossary is even further narrowed. A glossary definition is a “list and explanations of abstruse, obsolete, dialectal, or technical terms, partial dictionary.” Salesopedia boasts the most comprehensive sales glossary on the internet.
