With the exception of the
collections listed here,
newspapers are generally
not available full text before 1980,
especially non-US papers.
But older newspapers are
often available on microfilm
and can be interlibrary loaned.
There will be no index and
using newspapers on microfilm
is hard, time-consuming work.
To locate newspapers on
microfilm, use Worldcat:
country = subject
newspaper* = keyword,
limit = serial publications
format = microfilm.
Do NOT specify dates.
