I have a Sony reader that allows me download books from the library directly to my Sony library without the ADE step. I just purchased a Nook for my mother and it is requiring me to go through the ADE step every time and then drag to the Nook. Is there a way I can have the downloads go straight to the Nook?
When you say your Sony library, do you mean the library in Sony Reader software on the PC/Mac,
or do you mean the library on the device itself?
If it is a Nook tablet, try installing the Overdrive app.
If it is a Nook eReader you may well find you need to go via ADE.
On my older Sony PRS-350 I need to go via the PC: either via Sony Reader software or via ADE.
I choose ADE, as that also supports other eReader devices such as my old Bookeen.
