The regularity of IR will depend on articles and information contributed by its readers. As support grows, additional measures may be taken to bring enthusiasts together more formally. In October 1992 members of the Provisionals and Surcharges Study Group of the Ukrainian Philatelic and Numismatic Society met in Philadelphia to explore the philatelic phenomena resulting from Ukraine's separation from the Soviet Union. Several distinct categories were identified as areas for exploration. The following is a much expanded version of those areas discussed in Philadelphia and are submitted here as one method to organize the provisional postal markings and usages of the new republics.
All areas are expandable.
Our desire is to develop a system of classification that would not only identify a postal marking, but would also be applicable to all republics. Since black is the main color used, surcharges without a color indicator will be assumed to be black. We would also like to see comprehensive handbooks published for each republic, based upon a standardized classification system, and disseminated as soon as possible.
