Some time ago somebody mentioned www.ditel.tpsa.pl, It is the official
Polish telecoms site. One can look up personal and business telephone books
there clicking either next to "klienci indywidualni" (individual people) or
"firmy i instytucje" (businesses). The individuals are grouped by name and
location (you ought to enter name in the field "nazwisko" and place in the
field "miejscowosc", and accept clicking in "szukaj" button).
It may be helpful to remind this address to those interested in that sort of
search.
Best regards to all list members,
