The Italy and Colonies Study Circle (ICSC) is dedicated to the study of stamps and postal history of the Italian area. It publishes a highly acclaimed magazine called Fil-Italia. According to the society’s website, the magazine is the only significant source of information on Italian philately written in English.
Fil-Italia was first published in 1974 by Colin Pilkington, who remained Editor until his untimely death in April 2002. The journal is now in its 49th year of uninterrupted publication. A detailed index of articles for all completed volumes (1-48) is available online. The whole archive has been digitised, and article reprints are readily available.
