As an experiment, we are publishing the newsletter in an alternative eBook format so that it can be read offline. Click on one of the links at the top of this article to download your chosen newsletter. We've kept copies of old newsletters so make sure the date is for the right newsletter!

The instructions for downloading it to your mobile device will vary according to the device. For the iPad Touch, iPhone and iPad you'll find you can use Apple's iBooks, Amazon Kindle or Stanza. For these tablets, you have different options:

• Click on the epub (or PDF) link below from the safari browser, and it will load the book and offer to run it in iBooks, or in your preferred reader.
•  email it as an attachment to a message  to an email account that you have on the tablet and  then select it. Once it is downloaded, you can tap it and opt to read it in iBooks.
• Use iTunes, dock the tablet and then select the 'apps' tab for your device. Find the eBook reader that you have installed in the list  (e.g. Kindle or Stanza) and  either use the 'add' button under the file-list, or Drag 'n Drop onto the file-list.
• Add the file to the 'Books' subdirectory of the 'Library' directory in iTunes by Drag 'n Dropping the file(s).
• Use third-party software such as Calibre to load the newsletter onto your tablet.

The newsletter is provided in two different formats. EPUB (the most usual file format for eBooks since it will scale to the screen-size of the device) and MOBI (Kindle and one or two others).

If you have succeeded in doing it with another tablet device or phone, then please leave the instructions in a comment.
