In your content Library, information is stored as three distinct elements: Articles, Products and Packages.
Articles are similarly structured to newspaper articles. They contain an identifying headline, and then detailed information in the body text. (e.g., PSAV general information a description of a general session setup, or hotel description)
Products are individual items with an associated cost (e.g., a Microphone or Projector)
Packages are groups of products, which make up an experience. (e.g., Three Screen Experience)
