Remember the good old days when you carried a backpack with hard cover or paperback books and filled your home with the read books in your library. Well the 21st century has solved that issue with e-readers. My e-reader of choice is undoubtedly the Ipad4.. I can load books into the cloud or directly onto my ipad for reading pleasure.
Just think of it, all the latest sci fiction loaded onto a 14 ounce device. No more heavy backpacks or shelf cluttering books all over. The cloud has become the library of the future. PLaces like archive.org and others gives you free access to all the sci fi and scinece books you could ever imagine. If you want newly released material you can always torrent the lates books and periodicals from the web.
Another wayTrash is minimizing.
