Another place to look for articles is Google's News Archive Search. They've been scanning in old newspapers from all and when over:

http://news.google.com/archivesearch/advanced_search

(change to 100 results & limit the time frame to maybe a year at a time, and plenty of results so you'll figure out terms and such to nail down some of the harder to find articles)

For instance 'Star Wars' from 1997-1998 gives 10,100 results.

add in 'Special Editions' gets you down to 1,570.

weird that adding 'Lowry' to the above gives nothing...

Note: go back to the main advanced archive search when ammending a query, for some reason if you update in the results page it looses the date field.

Note2: also if you stumble upon an article which is behind a paywall, take a sentence or two and search for that. Often articles were reprinted in another publication which is not behind a paywall.
