All the Harry Potter ebooks are now on subscription site Oyster by Laura Hazard Owen.
Laura reports the Harry Potter books are available on Oyster and Amazon. She says that Oyster has the spin-off titles from the original series where Amazon does not.
Both offer $9.95 per month subscription rates, where Oyster claims “over a million” books and Amazon over 700,000. After reading David Mason’s How many books will you read in your lifetime?, I am not sure the difference in raw numbers will make much difference.
Access to electronic texts will certainly make creating topic maps for popular literature a good deal easier.
Enjoy!
