# Hard copy and physical media Today I took delivery of a second-hand copy of The UNIX Programming Environment. I had been looking for a copy for a while, but as is often the case with these classic titles, they are becoming a little expensive to obtain. So, when I do spot them going cheaply I grab them. Not so long ago I acquired a copy of The AWK Programming Language in much the same way and from the same well known on-line source of pre-loved goodies. ## Why hard copy? It's a welcome break to the eyes to look at real paper, under real lighting conditions. E-ink is my second favoured medium and I am still waiting for mainstream E-ink monitors. To me this will be a real technology advancement, but I digress... I can read this medium whether or not I have an internet connection, electrical power or a computer or other device. I can also be sure that it will remain unaltered and available as long as the physical media exists. As we know from the Amazon debacle, and others. When we purchase non-physical media or stream we don't own it and depending on cultural or political pressures it can be modified or disappear. I can't help but think of Orwell's 1984 where history is rewritten to align with the current narrative... For this reason I have a reasonable physical library which I continue to add to with what I consider useful classic books, CD media for music and DVD media for movies and documentaries. To the fellow who saw those O'Reilly books in the thrift shop, if you read me. Maybe you should reconsider that AWK book?
