I have a large binder where I keep all my iris info. One section is for maps. Each garden has its own page with a map drawn and irises listed in it. Notes at the bottom keep track of previous irises and issues with irises planted in that particular section. As I go about planting I keep a clipboard with me to make notes. During the winter months I enter the notes into the proper place in the binder. I have spreadsheets on the computer with irises listed alphabetically by class, such as TB, BB, etc. These iris names are followed by height, hybridizer, year introduced, year I received it, where I acquired it and where it is planted. I update this list during the winter also. This winter I am going to make sure the records on the computer dovetail with the plant list I keep on ATP.
