I have to admit, that’s a real downside of ebooks… Scrolling through your library to show off is surprisingly unimpressive.
I had a library that took up several rooms. The downside was that moving became a nightmare, especially moving to a different continent. I shipped my library to India when I moved and while there paid someone to digitize the whole thing. It took them about 7 years at 8 hours a day, six days a week. It cost me about US$115/month. I donated all the hard copy books to a traditional school, they created a new wing just for those books.
When I moved back to the West it was a cinch, it was all on my hard drive.
So that is the upside to digital books. They don’t tie you down.
