I guess you wouldn't be interested in Czech books ;-) Although I have good
experience with finding any photographic information in the 20-volume
Enyclopaedia of Photography from Focal press, including strange, forgotten
techniques (it's dated ~1970, so still lots of SpeedGraphics photos!)

I am sorry, but the film I was talking about was long discontinued, I have
only about 10-15meters in my fridge. It was ortho chromatic, propably. A
similar film, Foma Dokument Pan, made by Foma Czech rep., was discontinued,
to my big regret, 2 years ago. It was ortho or even panchromatic, can't
remember.
But both of the films were dokument films used in many fields like
microfiche archiving, scientific photography, etc., so perhaps checking
with few suppliers of graphic materials for print companies (or is printing
completely digital now in America?) scientific materials or such could get
you some local similar emulsion, maybe cheaper than Technical Pan. Or if
you know any nearby producer of film (there are not many independents in
the "Western" world now).
Or contact suppliers of film for the movie industry. There must still be
somebody in the world who makes direct positive film for B&W movies (this
is the stuff B&W pro 35mm or 16mm films are copied onto for projection).
This film is around ISO 1-3 !!! Propably would need lot of experiments to
get "right" contrast and exposure. And comes in very big rolls ;)
Propably the only "comparable" film you will be able to get will be Kodak
Technical Pan, which (depending on needed contrast and development) is
exposed and developed from iso 6 to iso 50 ? The special developer for it
is Kodak technidol liquid or such, propably very expensive. But cheap XTOL,
according to Kodak's datasheet, can be used to develop Techpan to normal or
lower contrast (sic!), if the film is exposed at 6 - 12 iso, if I remember
it right.
Look at kodak's web, there are datasheets on both XTOL, technidol liquid
and Technical pan. I would much like to get more of the Dokument film I
talked about, but FOMA (the film producer in my country stopped responding
to my queries about it ;-)
BTW, they still make orthochromatic (so suitable for some darkroom
safelights) copying film in list sizes, up to 50x60cm !!! If anybody wants
to make such a huge B&W slide or negative, look at <http://www.foma.cz> .
They also make "old technology" 100 asa film, Fomapan 100 (traditional film
similar to perhaps older Ilford FP4 or FP3), in sizes from 35mm cassettes
and bulk rolls (even 50m) to list film 50x60cm, at prices locally about
2-4x lower than Ilford's. So if somebody needs that cheap 50x60/10 sheets,
I could propably send it somehow.
