[5] Owned by Lehmann and Christopher Martin, the IMS had offices in St. Louis, Missouri and King's Lynn, Norfolk, England.
[7] In 1977, documents from the IMS supposedly supporting the legitimacy of the Most Serene Federal Republic of Montmartre were used in a court case by Montmartre President Barry Alan Richmond to advocate for the micronation's inclusion in the phone directory of New York Telephone.
[8] The IMS contributed its research to Erwin Strauss's 1979 How to Start Your Own Country about micronations.
[6] In 1996, Swiss author Fabrice O'Driscoll of Aix-Marseille University founded the French Institute of Micropatrology (French: l'Institut français de micropatrologie) as an unofficial continuation of the IMS.
[10][11] In 2000, O'Driscoll wrote the book Ils ne siègent pas à l'ONU: revue de quelques micro-Etats, micro-nations et autres entités éphémères (They don't sit at the UN: a review of some micro-states, micro-nations and other ephemeral entities), which details over 600 micronations.
