ReviewIt started in 1829 when the first book was published, The aim was to print all known medieval documents concerning Sweden, As of 2020 the documents of 1381 was presented in this book, the latest in this long going series.. The speed of publishing is not great, but we could have reached a bit longer, if it wasn't for a side project they had for decades, It will take between 200 to 300 years to get to the year 1400.. Comparing to books from the 1800's a lot has happened, and the modern books are a joy to read.
