Hans Dagobert Bruger was one of the pioneers of the Early Music movement. This is really meant for a 10-string Wandervogel lute, a/k/a German guitar-lute, or as I tend to refer to them, a Panzerlaute. Segovia used this book as his resource for his first JSB arrangements.
Here is a recording (on 6-string) of the BWV 999 prelude based on Bruger's version in A minor, which is the first piece in the link you provided:
Bruger was the first one to publish(1921) complete lute works of J. B. Bach.
It is more a reproduction(a translation from manuscripts to modern notation) than an arrangement.
As a source it was not only used by Segovia but also by almost all cg players(including me) playing Bach until Zuvini & Zerbroni came with ¨Opere compliti per liuto¨(Paolo Cherici) in 1980.
