CITCEM is an acronym for Centro de Investigação Transdisciplinar Cultura, Espaço, e Memória which Google says is
Center for Transdisciplinary Research Culture, Space, and Memory
Our part is under GHP - Grupo de História das Populações which Google says is Population History Group.
So really it's CITCEM - GHP. You can do a search for "citcem ghp" and it will pop up. But it's probably better to bookmark it:
For the Azores, it's mostly Pico and Faial (missing 1 freguesia on Faial). They did work on Corvo, the smallest island, and one freguesia on Sao Jorge. There's a little bit of the continent of Portugal. If you use Tombo.pt and the Azores GenWeb, it's cross referenced there.
I don't recall how many years ago it may have been. Perhaps 25 years or something in that ballpark. Someone at the University of Minho had the idea to create an index of the population. The work was done by university students. Celeste Perry, who is in her mid-80s now and no longer contributes to this list, was there doing her own research. They were talking and whatever else students do when completing what was probably a boring task for them. So there are errors. It's always best to go to the original record to see what the record really said. They do accept corrections. I'd have to poke around. It was somewhere on the bottom of the website.
