Along with riding instructor Vanda Oosterhuis, Lex van Keulen wrote an extensive book covering all major topics of breeding, keeping, training and riding Icelandic horses. Originally published in Dutch The Complete Guide to the Icelandic Horse appears in English. At almost 400 pages, it’s the most comprehensive publication on the breed available in the English language – the official language of FEIF (the International Federation of Icelandic Horse Associations)
