Finally there is a first English language version of a computer program for archive the sundials, that works with Windows 95 and NT: his name is AQS95. The program is TOTALLY FREE, AND PUBLIC DOMAIN, so you can use it for your own catalogue or for a National one, without restrictions. And last but not the list, without spend a lot of money for programs that will let you read the archive of someone else. AQS95 is useful for National census, and for personal archive as well. Can be used by gnomonists that dedicate them self to the study of a peculiar kind of sundial, and it is ideal to have an interchange between all of them without changing software language.
