"We wanted people to actually get the book if they saw me at a reading," he said.
In addition, the younger Brand said, he and his editor realized that readers often wanted a physical copy of the book, in some form, to hold onto.
The handmade, paper copies are intended for collectors, according to the website of the younger Mark's publisher, Chicago Center for Literature and Photography.
The younger Mark said sales of the book were good. The first run of the USB devices was nearly gone; 50 were printed about two months ago, of which ten or so were left.
He said there had been more than 100 downloads of his book. Though this figure might be understated, the younger Mark said, because a single downloaded copy might be shared many times over due to the nature of the medium.
He did not say how many people voluntary chose to pay for their downloaded copies. But he did say that each copy of the book, across all different formats, brought in, on average, approximately $10.
The younger Mark said he felt gratified to have his work highlighted in the ILCS library display.
"I saw the display and there were some really great titles I was proud to be alongside of," he said.
The display was up from near the end of April to near the end of May, according to George DeChant, an ILCS library media specialist. It was created byRichard Corrow, a junior who has a passion for science fiction.
Robin had showed DeChant the USB version of "Life After Sleep," DeChant said. Because he was so impressed and the novella fit the display's theme, it was included.
"People say all the time there will not be librarians in 10 years because there will be no books," DeChant said.
He disagrees. If librarians embrace new technology, they will stay relevant, DeChant said. And to some degree that's what the experiment that is "Life After Sleep" represents.
