We are reorganising the way we present things on this web site in 2019.
Instead of uploading all the articles from some editions as they are published, we will be releasing several articles a week.
You should find a new article, on the web site most days.
Meanwhile, we will be uploading all the papers in PDF form, so you will still be able to read all the articles printed online.
By uploading all the articles from some editions we have created many duplicate articles on the site when the same article appears in multiple editions. The search engines, such as Google, downgrade us for this. Conversly there are articles in other editions that we have not been uploading.
