The title I searched for on the eBook site is Oscar Wilde's The Picture of Dorian Gray.
Librivox had two entries, one was a work still in progress. You can download the whole book on to your computer, subscribe in iTunes, or listen to a podcast. There is also a link to the Gutenberg e-text. The same title on Project Gutenberg had five entries, three in English, one French and one Dutch, in print ready to read online for the use of anyone anywhere at no cost and with almost no restrictions whatsoever. You can also download for free. Google Book Search was excellent, yielding umpteen entries in different languages, and at different levels. Most had pictures of the cover, book details, and links to bookshops and libraries. The first entry had the full readable text, while others had only snippets. Reading my books online is not for me, but as a try-before-you-buy option, these sites would be very useful.
