Below are online available books and ‘how to’s that I have found and accumulated over the years. I have just started uploading them and it will take some time to do it, so keep checking back! They are mostly .pdf files that you can open and save on your own computer. If you come across any great free resources, feel free to leave a reply below so others can find them as well.
Keep in mind that when you click on them it will open up in a separate tab.
