To find out whether or not we have access to a particular newspaper, start with the Journal Title Database and search the name of the newspaper there. You'll see if we have any access to the paper (online or on microforms) as well as the dates our access covers. Sometimes you can search within that newspaper right from the search results screen, but that will usually only search against the most recent few years. Otherwise click through the source that includes the date range you need and search there.
For information about databases providing access to newspapers and other new sources, visit our Newspapers and Current News Sources Guide.
If we don't subscribe to a newspaper where an article you're looking for was published, you can request the article through Interlibrary Loan, but you will need the precise date of publication, and ideally the section and page number too. You can use Discovery Search to try to find a complete citation (be sure to click the checkbox "Expand My Results" to search libraries worldwide) or try Google.
