You can download the desktop software for the Reader ("eBook Library") from Sony and install that. With that installed you can:
- Try out the Sony store (just browse or buy a book)
- Download and start reading some the free books available from the mobile read upload section.
- Try out some of the tools available from here to convert your own text files, PDF's, etc to a format suitable for the Reader (the eBook Library software has a display that will show you what a file will look like on the Reader). See the "Content" section of this forum for details.
You can also start collecting free books from many sites. See this thread for some starters:

If your local library supports checking out electronic copies of books in secure PDF or Adobe Digital Editions format, you can set up an account with them. (You'll need to download the free Adobe Digital Edition software and install that.)
Welcome aboard!
