Description: This function determines whether a library exists and returns a boolean result. Keep in mind that libraries often have one name that is visible in the Finder and a different name that is used for access. To determine the required name for LIBRARY statements, use a resource editor like Resorcerer and examine the _"cfrg" resource. The proper names for many common libraries can be found under the help menu in the manual named "Mac Libraries."
