Help me, LJ Braintrust, you're my only hope

Hi, a great question for my helpful scriby friends out there,

I'm looking for a good beginner's guide to learning period hands, such as Gothic bookhand, Textualis/Textura.

Would these be good books to start with?
Medieval Calligraphy: Its History and Technique by Marc Drogin
Or this book
Learn Calligraphy: The Complete Book of Lettering and Design (Paperback)
by Margaret Shepherd
