J. Theodore Bent & Mabel Bent 
Southern Arabia [PDF ebook] 

First published in 2005. J. Theodore Bent, well established as a travel writer and archaeologist, made seven journeys in all around the southern part of Arabia including Oman and Dhofar. Accompanied always by his wife, the author devoted the last years of his life to observation and travel in these lands. This account of the couple’s travels, first published in 1899, two years after Bent’s death, is a fascinating picture of the lands, peoples and history of Southern Arabia.
