Do you read any journals published by Cambridge University Press? If yes, you may be interested to know that CUP is celebrating 15 years of journals online with an offer of free access to selected articles. Just visit the home page of a journal you follow, and click on the gold tab labeled "CJO Birthday Offer" for a list of free articles. The offer is good until 3 October 2012.
Here are a few journal titles that I am familiar with:
International Review of the Red Cross: 1961-1997 Archive [access]
International Review of the Red Cross [access]
- Although note that the ICRC web site provides free full-text access to issues dating back to 1997.
Prehospital and Disaster Medicine [access]
Yearbook of International Humanitarian Law [access]
