This is the third in a projected series of five volumes dedicated to the work of the Adriatic Islands Project (AA). The first volume, The Archaeological Heritage of the Island of Hvar, Croatia was published bilingually, in English and Croatian (Gaffney et al. 1997). The second volume, The Archaeological Heritage of the Island of Brac, Croatia was published in English (Stanèiè et al. 1999). This volume builds on the achievements of these earlier publications. The work utilises, essentially, the same research methodologies developed for survey on Hvar and Brac. The continuing reliance of project staff on complex computer technologies to store and analyse the large project databases also remains, and the impact of the increasing sophistication of thesetechnologies for display of data can be seen in this publication. This book, covering prehistory to medieval times, is divided into two parts, reflecting the diverse nature of the areas under study. Part one deals with the most remote island group that fell within the project study area and includes the island of Vis and the smaller islands that have for centuries been associated with Vis; Bievo, Svetac and Palagrua. Part two deals specifically with the island of olta. olta lies just west of Brac and is the part of the project study area that is nearest to the mainland.
