Reddit reviews The Historical Source Book for Scribes

For me, books. There are a lot of paleographers and calligraphers who have devoted a lot of time analyzing historical manuscripts and tracing the lineage.

Some good ones:

Historical Scripts by Stan Knight

Medieval Calligraphy by Marc Drogin

The Historical Source Book for Scribes by Michelle P. Brown and Patricia Lovett

Those are just a few. There are plenty more good ones! Also, getting into script analysis yourself can be very helpful. Start looking through the manuscript section of the sidebar and making your own observations. It can be quite illuminating.

I think I know what you mean. For broad edge, I'd suggest Michelle Brown's A Guide To Western Historical Manuscripts. I'm not sure what the answer is for pointed pen.

Brown's book is meant for paleographers (historians who read old manuscripts) not calligraphers, so it won't have anything like a ductus or comments on how to do the scripts inside. What it does have is a crap ton of scripts, laid out in high-quality full-page photos from the original manuscripts in a nice large format.

If you want instructions for how to do said scripts, I'd recommend The Historical Source Book for Scribes, by Brown (again) and Patricia Lovett, an accomplished calligrapher. This won't have quite the breadth you're after (it only has 14 scripts vs. 55 in Guide to Western historical manuscripts), but I think it's a valuable starting point to learning scripts from just a manuscript, as I talk about at length here (that comment also has some links to online libraries with extensive digitization projects; it takes some work to get what you want out of them, but once you do the selection and image quality is miles better than any book).

If you can't find an affordable copy of "historical source book" (the price seems to fluctuate wildly), Drogin's Medieval Calligraphy is not as good, but still a good starting point. And it's super cheap.

Also, I wouldn't recommend Harris' The Calligrapher's Bible. It's overdone in some areas and underdone in others, as I talk about here.

Sorry to link to my own replies so much, but I have a lot to say on this topic and I only have so much time to type :)
