YesThe analysis of organic residues from archaeological materials has become increasingly important to our understanding of ancient diet, trade and technology.  Residues from diverse contexts have been retrieved and analysed from the remains of food, medicine and cosmetics to hafting material on stone arrowheads, pitch and tar from shipwrecks, and ancient manure from soils.  Research has brought many advances in our understanding of archaeological, organic residues over the past two decades.  Some have enabled very specific and detailed interpretations of materials preserved in the archaeological record.  However there are still areas where we know very little, like the mechanisms at work during the formation and preservation of residues, and areas where each advance produces more questions rather than answers, as in the identification of degraded fats.  This chapter will discuss some of the significant achievements in the field over the past decade and the ongoing challenges for research in this area.The copyright situation is complex with this paper.  In the original copyright agreement I signed it says that I am allowed to post the title, reference and abstract to an open access repository.  Further investigation of the ACS website reveals that this is still the case with book titles but that we are also allowed to publish a link directly to the article by DOI (which I have pasted in above).  The website also specifically states that permission will not be granted to up-load articles onto websites.  Their new open-access policy I think only applies to journals rather than books, although that wasn't very clear.  I have however attached my final version, prior to peer review.  It is formatted for the volume as I was required to submit in that template.  We will not be allowed to up-load it/make it available, but it is there for archiving purposes if you would like it.  I believe the Library may be buying a physical copy of the complete volume when it is published later this year.  Please check with Sarah George to confirm.Full text was made available in the Repository on 15th Oct 2015, at the end of the publisher's embargo period
