Several of the project instruction links for example photos lead to blank screen see notes for link
If that link does not work, it is the Sierra Leone -Birth and Death Registrations, 1858-2016 [Part B][M39V-JHQ]
I am just another 'lowly' User/Patron.
As you are referencing an "Indexing" matter ...
Just a thought ...
Can I humbly suggest that you REPOST this post of your in, one; or, better still, BOTH, of the following places, rather than here under "Sources".
Here in the "Ideas' Section; but, under the "Topic" of "Indexing" ...
Home > Ideas > Indexing
As there is NO LONGER the 'Group' of "Indexing Chat" in the 'Groups' Section; as, there was ...
[ ie. Recently "Closed Down" ... ]
ALSO in the "Q and A" Section, under the "Category" of "Indexing" ...
Home > Help Center Categories > Indexing
You never know, some that follow that "Q and A" Section on "Indexing" may have some thoughts or ideas.
Again, just my thoughts.
