Many article databases such as LexisNexis and Factiva do not provide access to older content from newspapers. Typically, historical coverage of newspapers titles in databases tends to only extend to the 1980s.
That said, the NYU Libraries does have access to many important historical, international news sources, and some historical international news archives are made freely available online. This page will help you to locate these.
If NYU does not own a book, newspaper, or journal, you can borrow from another library using our Interlibrary Loan Service. Note that you may also borrow microfilm reels of historical newspapers.
Most of these historical, international news databases include digitized ("as printed") PDF versions of the newspaper, while others may contain only the full text. If you don't see the specific country you are searching for represented in these databases, try one of the databases with global coverage.
