[ swiss miss ] A big part of learning how to work with a Greek New Testament is talking about scribal errors that are made when taking one document, and painstakingly making a duplicate copy of it. In the early days, it would be manually copying one document at a time, and later (it seems), someone would sit in a room reading the document aloud while a group of people each made a copy!
Copying technology dates back millenia, but did you realise just how old the technology behind the laser printer is? The office copier turns 50. (Note: a laser printer is just a smarter version of a photocopier – learning this was one of the first assignments I had at uni).
