I would like to see if it is possible to obtain a copy of the book below which may be out of print, in some kind of digital format. I can see a copy in the internet archive https://archive.org/details/latinwithlaughte0000char/mode/2up but there doesn’t seem to be any pdf or anything like that that I can track down. I have written to Heinemann the publishing house as well but thought to see if anyone in the Textkit community would have some knowledge on it.
It would be tedious, but you could borrow it from the Internet Archives and screenshot each page. Then you could convert the images to pdf and combine them.
There is a method to download pdfs from archive org, but I think this is not the place to expose it. I have the file, I have downloaded it for you, if you are still interested I just need to see where to post it. Greetings!
