Thank you so much for that.

For the benefit of any other disappointed buyers of the Kobo Touch, here are the steps:

1. Delete each of the PDF books in the Kobo.

2. If you have not already done so, in Calibre, click on the name of a PDF-book, and convert it to EPUB.

3. Still in Calibre, click Edit Metadata, and in the top right-hand corner you will see a box showing both the PDF and the EPUB version of that book.

4. Click on the PDF-version. To the right of that window, you will see a triangle made up of green arrows -- click on that to 'Remove selected version for that book,' then click OK.

5. Switch on the Kobo, connect it to your computer, and press 'Connect' in the Kobo window.

6. Once Calibre has recognised the Kobo, click on the book that you want to send to the Kobo.

7. Do NOT click on the 'Device' icon to carry out this exercise. If you do, at any rate if your experience is like mine, the procedure will fail.

8. Instead, find 'Send to device' in the Calibre menu-bar, click that, then 'Send to Main Memory.'

9. Allow the Kobo a few seconds to complete the process.

10. In my case, I now have each of my once-PDF books, but now EPUB-books, in the Kobo.

11. In the case of 1 or more of the books, the picture on the cover is shown upside-down, but with that qualification the Kobo reads all of the EPUB-versions perfectly.

I am truly grateful to you for your help with this, without which I should have been giving what in England is a $150 ereader to the local charity-shop.

Well done !
