The code of a sermon composes of three numbers:
The first indicates the collection.
The second the edition on which the description is based.
The third the position within the Lenten sermon collection.
The first and second number form the code of an edition

For instance, the code 1/2/18 indicates that the sermon belongs to collection 1 (the Quadragesimale by Gritsch/Gruetsch), its description is based on the second edition (1/2), and that it is the 18th sermon of that Lenten cycle.

Note: collection are numbered randomly
