It seems that there is more than one word for table in the Nordic languages. You have table as in table and chairs, which is bord. Then you have table as in an Excel table, which is tabell. Interestingly, tabell seems to be derived from Old Saxon via Anglo-Saxon and Old English. It's a good thing Lars is an expert. I edited the paragraph in Chapter 5 to reflect my correction.
A couple of readers pointed out a dating technique for large pieces of wood. Dendrochronology examines tree rings and compares them to known samples. I had heard of it but forgot it. They'd need samples of a tree brought with them - like the keel or mast of a longship! Interesting idea! I added a small section in Chapter 7 to reflect it.
Another reader pointed out that iron from India did make its way to medieval Europe in the time frame being discussed. I changed that reference to South Africa. That was Chapter 6.
For those who have already bought a copy of the book, if I add to or edit a chapter, don't worry. At the end of the story, I will upload a final fixed version to bookapy, etc. and let everybody know via the blog. You'll be able to download an updated version at that time.
