What is hidden

The books we did buy till now, remained, till we gave them away or, eventually put them in a bin, on our shelves.

For all to see.

Some books we did put on front, for all to see, others in the back or up to the highest selves.

The electronic books we buy by one click, are a lot more hidden. "No one can see them!"

I just read a paper found in underground newspaper that nowadays, more then 50% of some kind of books are those sold for electronic devices like the Kindle. Well, some we do not want on our selves but are curious or eager to read inside a small device.

Same book, hidden "under" cover... With time, they are even more hidden and forgotten then those from behind gathering dust.
