British Library Newspaper Resources:
http://www.bl.uk/eresources/newspapers/colindale2.html
This is a fantastic resource offered by the British Library but you will need a British Library Readers Card to access them from outside the British Library. This provides remote access to a number of newspaper archives not available through the Robinson Library and includes Early American Newspapers Online, Australian Newspapers Online and others.
Dutch Newspapers Online:
A fantastic resource if you’re working on anything relating to the Netherlands, this archive provides free access to Dutch language newspapers from 1600-1900. The site is not in English but judicial use of Google Translate can help you navigate it without much difficulty!
Other Newspaper Archives:

Wikipedia has a fantastic list of online newspaper archives, both historical and modern. Many of these are behind pay walls and are not subscribed to by the Robinson Library, but a good number are free to access by anyone.
