Cuba: Online Research Sources

In trying to find information on Cuba's use of bisected stamps, I came across two resources that I thought may be of help to Cuba collectors:

• FILACUBA - a website dedicated to the study and promotion of Cuban Philately. The site contains an extensive bibliography.

 

• The Pichs Collection - an ongoing research and exhibition effort to study and bring to the public an important research resource for the cultural history of Cuba, the Roberto Pichs collection of Cuban postage stamps at the San Carlos Institute (Key West, Florida).

Please add your online Cuba reference sources to this thread.
