You can compare different sources or ideal forms with each other. It is possible to select up to four tables to view simultaneously. The sources will appear on the screen in the order of your selections, which, however, does not affect the content of the comparative table: all records from all the selected sources will appear.
After having selected a tradition on the left the sources available in that tradition will appear on the right side. If it is available, the ideal form of the tradition will also be included in the list.
