Mary Sue: I think you would need the code system for books containing numerous genus. In that case a code or a two letter designation could be used to refer to each book. Books that are a single genus like the Cyclamen or the Galanthus work could be listed as just that. For example for the Phillips & Rix book it would be { PR} On the Fritillaria sibthorpiana image link would be PR page 95 or something like that. On the Galanthus elwesii image link would be PR page 13, 15 or BDG pg. 7, 32, 166, 341 ( Bishop, Davis & Grimshaw) A Monograph of Cultivated Galanthus I would hope that we could designate one person or a team to upload the reference material for each genus. I think the format would be critical going forward. Time should be spent getting it right before the time is spent to create the references. Now any volunteers? Arnold
