library vs. bookstore

Something that just came to me.

I wonder, how do authors feel about readers who read their books via library loan vs. purchase? I mean everyone wants to be read...does it matter if the reader purchased their book, or borrowed it from the library? I will admit, I cannot afford to buy all the books I want to read. Although there are some authors whose books I'll purchase simply because I've read everything they've written, and have enjoyed each one [Holly Lisle, S. L. Viehl]. Does it really matter? I purchased 1/2 of the Vampire Huntress books, but read the last 4 as library copies. I will buy them eventually...but I didn't want to wait until my wallet was feeling cooperative.


Just curious...what are your thoughts on this?
