when the magazine "Accordéon et Accordéonistes" existed, I had scanned almost all the pedagogy courses. I had created a folder with .htm files (which open in your internet browser) containing hypertext links calling pdf files which are in the "Contents" folder. To make it simple it works like a website but locally, that is to say without using the internet connection. Procedure to get this local site:
1) download the file (it is 1,5Go)
2) unzip it (with winrar, 7zip, Winzip, Powerarchiver or others... ).
3) once unzipped you get a folder "Accordeon_&_Accordonistes_Pedagogie" that you can file wherever you want on your PC. Then you just have to open this folder and click on SUMMARY. Your internet browser will open and you will be able to navigate through all the courses and articles proposed in the different sections. I hope you will find this interesting.
Have a good reading
