But the "value" of a first edition varies from person to person. I attach no value whatsoever to a first edition of a book, and I'm not the only one.
A digital edition of a book is still superior to a paper book for archival/saving purposes because a paper backup can be easily printed out at any time. Much harder, I think, to duplicate a paper book.
