Do the others Scott, Michel and so on list them? Scott does not, in fact Scott is very basic in its coverage. Michel produces a Great Britain specialized catalogue which parses out Machine quite extensively the way Gibbons Decimals 2 does, but not sure if paper fluorescence is covered - I think more focus is on the many varieties of tagging bars used over the decades as far as UV elements are concerned. Thank You. This UV is a fascinating topic. I teach classes in forensics and alternative light photography but I never use it on stamps. I have 2 videos I call "If you teach forensics do not bring the UV lights back to your hotel"

The Australians are also VERY heavy into the different flourescent papers that were used to print Australian stamps (definitives and commemoratives) in the 1960s and 1970s. All listed in the Brusden-White Decimals 1 catalogue for Australia

Maybe a little late to this thread but one website to cover two points. brixtonchrome.com/blogs/canadian-stamps-and-postal-historyThe website has details about Canadian (some others) in their blogs that are not covered by the catalogues (including Unitrade). Paper types and paper fluorescence is a specialty. Not all the time do I agree or understand the types mentioned but the blogs certainly set the stage for your own sleuthing. Second point is that these blogs are (at least to now) freely available. So many of the references mentioned in SG and Michel are not available except if you belong to a specific philatelic society. I already belong to 6 just so that I can get their literature. Of course Stamp forum is also a useful reference.
