Congratulations to Penang Digital Library!
A digital library should offer 24-hour services online. There are no physical books at the facility, but there are 3,000 e-reading materials available for free.
As far as this author knows, this is the first public library to open its doors to the public for 24 hours. And for a very good reason.
The Digital Library is located at 135, Jalan Masjid Negeri, Taman Guan Joo Seng, 11600 George Town, Pulau Pinang.
