Illustration: Multiple instances of study objects in production libraries

Study objects, including forms and items, can appear multiple times in a single library and can also appear in other libraries. For example, in the illustration:

• The following forms were copied with the Copy > Link option:
  • Vital Signs—Appears in both the Arthritis and Migraine libraries.
  • DEM—Appears in both the Migraine and Cholesterol libraries.
  • Adverse Events—Appears in all three libraries.
• An item may be in a library in multiple places. For example, the itm_wgt is:
  • In the Migraine library as part of the Vital Signs_2 form.
  • In both the Migraine and Arthritis libraries as part of the Vital Signs form.
  • In both the Migraine and Arthritis libraries as a standalone item.
