Sundari ... would like to suggest you a tip while getting books..if at all you dont mind
For these kind of tamil novels you better opt for good publications in and around T.nagar rather than falling into hi-fi stores..some famous publications are "vaanathi pathipagam".."kannadasan pathipagam"...
1. You have a wide range of options in these stores..similar author, similar back-ground... and various editions are available for the same....they are cost effective too
2. this encourages the small small merchants whom are very much dependant on the income gained out of it.
