Cranium and Synapse enable you to assign a reference to almost every datum entered into a document. Although this reference can be any character string, it is typically the identifier of a reference entity.

Reference entities are stored and managed in the References chapter. All documents have a References chapter.

The chapter's datapane is divided into six sections:

Section	Description
Descriptive Information Section	contains descriptive property fields for the title, authors and keywords.
Document Location Section	contains a single field that stores the online location of the document associated with this reference. The location is typically a file name or a web address.
Source Information Section	contains several fields used to store and display the References source.
Publisher Information Section	contains fields for storing the publisher's name and location.
General Notes Section	used to store any general notes about the current reference. Often a brief summary of the Reference's physical property contents is entered in this field.
Associated Documents Section	used to store links to any documents associated with the current reference.

The References chapter has commands for reporting, compiling and displaying references. These commands are available from the chapter's Commands menu.

• Report Reference Properties: activates the Report Properties Dialog that enables you to select properties and attributes to add to an open Report Document.
• Show Valued Properties: activates the Valued Properties Dialog: which lists the current reference's properties that have one or more values.
• Create Bibliographic Entry: activates the Bibliographic Entry Dialog which combines various Reference property values into a standard citation format.
• Import Citation File: activates the Citation Import Dialog which will parse an RIS formatted file or text string into reference entity attributes which can be stored into the current document. This command can save considerable time and effort when entering a new Reference.
• Compile Source Counts: activates the Source Counts Dialog which lists the number of times a particular publication source was cited by a reference in the current chapter.
• Compile Keywords: compiles all the keywords used by all the references in the current chapter and then displays them in the Compiled Entities Dialog.
• Compile Authors: compiles all the authors used by all the references in the current chapter and then displays them in the Compiled Entities Dialog.
• Reference Usage: activates the Reference Usage Dialog which displays all each datum citing the current Reference.
• Show Reference: opens the document stored in the current reference's document location.

The menubar provides numerous other commands for navigation, bookmarking, file operations, units conversion, etc. See the documentation on Common Commands for details.

Additional documentation on displaying, editing, copying and pasting property values can be found in the introductory documentation listed in the Related Documentation section below.
