The search facility is available for the weekly editions. HOL is available free to the readers. This is made possible thanks to the advertisers. While the individual advertisements appear at random in various section indices and in stories, the index of advertisers is a full list with links to respective advts. As an essential feature in all sites, this lists various changes in and milestones of HOL from the start.
Improvements are possible only through feedbacks.
A link between the reader and HOL is established through this. Through a simple form, readers' names, email and comments are captured and sent to The Hindu office at Chennai for necessary response.
