I worked as a British scientific civil servant for about 20 years, and during that time I published a lot of scientific papers all of which are British Crown copyright. Fortunately, Her Majesty's Stationery Office (HMSO) has very liberal views on allowing the reproduction of Crown copyright material. This has made possible the creation of this on-line archive which contains retypeset versions of all of my Crown copyright publications.

Thus far this archive contains all journal papers, conference papers, book chapters, and (publically available) reports that I published whilst I was a civil servant.

For reasons that will become clearer as the scope of www.luttrell.org.uk is developed in the future I use Mathematica as my main tool for authoring documents. For those who do not have Mathematica you have to use the freely available Mathematica Player to view Mathematica notebooks, which is no more difficult than using the Acrobat reader to view PDF files. However, note that Mathematica documents do not display themselves natively in your web browser, so a separate window will open on your display screen. A future development of this archive will use XML features to display everything natively in your web browser.

Each paper in this on-line archive is a Mathematica notebook, but I have decided to put the figures in external files that are reached via live hyperlinks to reduce the bandwidth needed to download the paper-without-figures, and all cross references within and between papers are reached via live hyperlinks. Separating the figures this way is a bit of a mess, but it is only a temporary arrangement, and will not be necessary once bandwidth and disk space become cheap enough.

I have yet to do the final proof reading of the retypeset papers, so there will be residual errors. I will correct these problems as time permits.

Future additions to the archive will include some or all of the following:

1. It is not yet clear whether I am free to republish any of the documents that I wrote since I ceased to be a civil servant, but as soon as I know what the situation is I will act accordingly.
2. There are some papers that I co-authored whilst doing my PhD in theoretical physics circa 1980. For the cognoscenti, it was on higher twist effects in QCD, which was a very instructive period I spent doing operator algebra. When the copyright in these papers has expired (very soon now!) I will upload them to the archive.
3. There are lots of slides that I have used in various seminars, talks, lectures, etc over the years dating all the way back to my PhD years. On rereading these slides I notice that they contain useful information that was never included in my published papers; sometimes because of lack of space but usually because of disagreements with referees.
4. There are lots of papers that never made it past the referees. Unfortunately, several key papers of mine fall into this category, which has made writing/publishing subsequent papers quite a difficult process. Amazingly, the original Adaptive Cluster Expansion (ACE) paper was never published because of reluctance by referees to think outside the "box"; I want to make this sort of paper available.

I have decided to start publishing to the excellent arxiv.org e-print archive; here is my first submission. The arxiv.org repository is good for several reasons:

1. It is on-line and makes the fruits of your research immediately available to other researchers.
2. It ensures that controversial material is available to others; arXiv.org seems to be fairly sensibly policed to exclude obvious garbage without rejecting potentially good papers.
3. It date-stamps your preprints; rather important in those prickly little priority disputes.
4. It provides a permanent archive of preprints; arXiv.org is widely mirrored and seems to be a safe repository for all time.

I intend to add LaTeX versions of my Crown copyright papers to this web site so that it becomes a sort of mini arXiv.org; I suspect that the arXivians would not be too amused if I simply dumped all these old publications on them, so I will keep these publications as a separate arXive.  If web space allows I will also include PS and PDF versions of the papers, which will (hopefully) be picked up by the various clever cross-referencing engines to link them in with the rest of the literature. Is this too much to hope for?
