This book is often part of the permanent collection of many LDS Family History Centers, in microfilm or microfiche format. If it is not a a Family History Center near you, it may be ordered on inter-library loan for a modest fee. The microfiche format is the least costly and becomes a permanent part of the local library's collection if it is ordered. I have not found the book contained information about my own surnames, but the maps are interesting and the history is also interesting.
