what is digital library? How it can be used? what is the basic needs to be used?

Answer 1

A digital library is where everything you want is online in some form.
Some digital librarys subscribe to not only ebooks but have magazines, music and of course all the information from the webs.
The library by my home (has a digital site) you can "take out"
something and when it is due you can renew the item or they delete from your "library profile".
I hope this helps.
