Master list of documents

I've received this question:
After risk assessment and treatment, I come to find out that there is something called masterlist of documents. I would like to know much about it please. I am not clear about that.
Answer:
Master list of documents is not a mandatory document, but it can be very useful for the Internal and External auditors, because they can identify what the organization has.
The main objective of the master list is that the organization knows which documents exists in the ISMS. So, you need to identify all documents of your ISMS and then include it in the master list. For each document list the name, you can also include the person responsible, number of version and date of last change.
If you need to know the list of mandatory documents of the ISO 27001:2013, I recommend you this article “List of mandatory documents required by ISO 27001 (2013 revision)”: https://advisera.com/27001academy/knowledgebase/list-of-mandatory-documents-required-by-iso-27001-2013-revision/
