"A Natural History of Ferns" (Robbin C. Moran) might be useful. I also like "Fern Grower's Manual" (Barbara J. Hoshizaki & Robbin C. Moran) and "Encyclopedia of Ferns" (David L. Jones). Are you a member of the British Pteridological Society? They often list publications that appear to be interesting. If you have an opportunity to travel to the Southern US, we have a Georgia (State) College Botanical Garden near Atlanta, that has the most extensive collection of the world's hardy ferns in the US and the collection is probably rated in the top 3 in the world.
