Bohemia census

I read on the website:
http://www.toledot.org/hbftext.html
that
"Two different record collections were formed during the period of „administrative anti-semitism“, e.g. Censuses that were carried out horizontally in years 1723/1724/1729, 1783, 1793, 1799 and 1811, and so called Familiant books covering vertically three consecutive generations of Jewish Familiants"

Anyone one know how/where to access the 1723/1724/1729, censuses?

I think a publication is in process.
