Here’s what happens. I read something about an author I have interviewed in the past and then I want to look in their book to check up on something or just re-read a passage. When I was doing interviews at tompeters.com, books were sent from publishers or PR people, sometimes I bought them, sometimes the author sent them, and sometimes I was just reading a galley. In one case I printed most of the chapters of a book from pdf files. A waste of paper? Perhaps, but I must say that I still prefer to read from paper and prefer to make notes on paper. Just a condition of my age? Probably.
I like looking up at my bookshelves and seeing the spines of books I’ve read. I like being able to reach up there and pull one down. In some cases I don’t have a physical book. I may have just read a galley. But I always thought that an author I interviewed should have made sure that I received a hard copy version of the book if I hadn’t already got one. Not just me, anyone who interviews them. Or at least ought to ask the interviewer if she/he wants a good copy of the book. Or in this day and age, at least ask them if they want a kindle version. Can PR people send out Kindle versions of books the way they do hard copy versions?
Just a thought for you authors. Your interviewer may really like your book and may continue speaking about it beyond the publication of their audio, video, or text version of your talk with them. Ask your interviewer if she wants another copy/version of the book.
