how to share books

I don't often share books from my private library but I do exchange novels I've read with family/friends when we meet

if i read a good book i like to share it with all my family & friends

Since we live in the 21st century which offers some advanced options, so I keep digital versions (e-book) of my favorites and it's easy to share. ;)

Just Maintain a register or make an excel file or download any library basic freeware in which you can keep your record of books
