She lists the following publications on her website:
Books
Sturdy Colls, C. (In Prep.) Holocaust Archaeologies: Approaches and Future Directions. New York: Springer.
Hunter, J. Simpson, B. and Sturdy Colls, C. (In press). Forensic Approaches to Buried Remains. Wiley, London. (Due to be published in November 2013)
Sturdy Colls, C. (In Prep.) Holocaust Archaeology. [Expected to be published in 2013]
Sturdy Colls, C. (In Prep.) Finding Treblinka. Archaeological Investigations at Treblinka Extermination and Labour Camps [Expected to be published in 2014. In English and Polish]
If I were her though, I'd concentrate on one book at a time. Then she might get one of them finished.
Quite honestly, the sheer ignorance of academic publishing schedules involved in your post is truly remarkable.
Sturdy Colls' staff page is easy to parse. She completed a PhD
only last year in 2012 - the date of its award - having worked on several projects on the way, including on Treblinka, which has led to several publications already - which would have been submitted some time back, the 2012 publications would have been sent in for peer review in late 2011 or early 2012. The two papers on Holocaust archaeology to appear in English are general overviews, whereas the paper in Polish is specific to Treblinka.
For 2013, there seems to be a co-authored book of an even more generic forensic archaeology focus
in press, a book chapter on archaeology in general
in press, and another book chapter on her project about a camp in Alderney
in press, along with a translation of the 2012 Treblinka paper in Polish. In press means completed; the full manuscript submitted for editing. Another Treblinka paper is in press for a Polish collection; and one can then compare with the conference papers listed to work out that this conference paper was given in 2011.
As a recently appointed lecturer, Sturdy Colls is an early-career researcher and will need to submit one or at most two items - article or book - for the UK's Research Excellence Framework assessment exercise; she evidently will have a choice of about
7 items already under her belt, including one co-authored book.
There are evidently two more books on the way, one which would build on the already published 2 articles on Holocaust archaeologies
in general and could draw on the work done in her fellowship in the Netherlands in the autumn 2012 term. I count 5 or 6 conference papers in this vein. The book is supposedly in prep and due at the end of 2013. Whether it appears before the end of this year remains to be seen;
she does not need to publish it this year as she already has potential REF submissions. Career-wise she might be better off holding it back until 2014 and the next cycle, if it contains substantial amounts of new material.
Note that her bio states she has also conducted archaeological investigations at Semlin near Belgrade and has been advising on an archaeological project at Westerbork. This general book can also survey and synthesise the results of archaeological investigations of most of the KZs in Germany/Austria as well as the T4 euthanasia centres conducted in the past 10-15 years, as well as the results of archaeological investigations of Chelmno, Sobibor and Belzec.
Most of all, the general book can draw on her PhD thesis - thus this book is
probably already substantially written.
The other book is evidently the expanded version of her already-published papers on Treblinka in particular and is slated to be published in Polish and English. Since no publisher is listed then the chances are good that it might be in conjunction with the Treblinka museum or another similar body in Poland, as they would have a strong interest in such an item. Previous publications of archaeological digs at Belzec have not run to vast lengths but have been heavily illustrated with maps, diagrams, schematics and photos - things that journals might limit more severely.
Overall, this is the research and publication profile of a very successful early career researcher, who will likely have two books and multiple articles/chapters out within 3 years of completing her doctorate. She has benefited from at least one term of research leave in autumn 2012, which will have helped immeasurably.
My personal experience with publishers is that they demand long lead times. I am currently working on a book which should be finished in the early autumn of this year and will then not appear until late 2014, as the publisher in question doesn't like putting things out in the summer. Technical lead times could be as low as 5-6 months, but the publishing schedules can lengthen that for commercial reasons, based on their experience and knowledge of the (academic) book market.
I have seen several Holocaust deniers whine how-come-her-work-isn't-out, ever since the first publicity for Sturdy Colls' work at Treblinka appeared in January 2012, even though she was already talking about it at academic conferences in 2011, an article appeared in Polish in 2012, an English translation is due this year and another article is due then too, and a book promised within two years of the first news. Even if it stretches to three years, so what?
Compare this with Holocaust denier Richard Krege, whose 'survey' of Treblinka in October 1999 has simply never appeared.
