As this site publishes antiquarian books from a whole variety of sources you will find spelling of words in old Scots, modern Scots, UK English, American English and other varieties. This is not to say that we don't have spelling mistakes on the site but as you can see due to the many sources and contributors we have spelling is a problem depending on where you are based. We also OCR many books onto the site and while every care is taken to proof each page we will miss words. The main purpose of the site is to make available antiquarian books that are often difficult to find or are in rare book collections at libraries.
Should you be convinced that you have spotted a mistake we are always happy to hear from you. When pointing out a mistake please quote the url of the page where you found the mistake.
