For a non-literate society Vikings are good booksellers. There is a huge number of general books, many lavishly illustrated. I have largely avoided listing these, and have preferred instead to cite edited volumes of papers in English, many of which also provide accessible introductions to Scandinavian material. Most of these also have full bibliographies to other sources and primary evidence. Because of the rapid growth of new archaeological discoveries I have also emphasized recent works and generally avoided works more than 15 years old.
