Awesome! I found adding samples somewhat addictive at first, it's satisfying to learn this way. At least for the first 100 entries or so
The types are: Charter, Manuscript, Other. I see for example that Marco marked a letter as O for Other. We never really used this column though, but it's easy to fill in.
We introduced the date codes because you can't sort a column that contains various date ranges (1444; 1450-1460; second third of the 15th century...). So having these dates codes allows for easy sorting and counting by date range. They go from 0 to 5: one code for anything earlier than the 15th century, one for each quarter of the 15th century, one for anything later than the 15th century.
- 0: ....-1400
- 1: 1400-1424
- 2: 1425-1449
- 3: 1450-1474
- 4: 1475-1499
- 5: 1500-....
I generally avoided entries dated to "15th century" since we want some more detail there, at least half a century or a quarter. Of course, if a very good match is dated "15th century", it should be added. If a date range is provided like 1420-1460, just take the average and see where that date falls. In this case, it should be code 2 for 1440.
When you come across a MS with multiple scribes, just add a note of the page somewhere. (I believe I sometimes did this in the shelfmark field?) Either way in manuscripts it might be useful to add the page where you started looking. Generally, I don't stray too many pages from the one where I started looking.
It is not necessary to add all scribes from a MS, unless you think it's interesting. I don't recall how we handled this exactly, since towards the end of the project I was mostly focused on charters. Adding the page number should be sufficient.
