Are libraries the bane of publishing companies?

It would seem that every time a library obtains a book, it is allowing potentially hundreds of people to read it without paying. How do publishing companies deal with this? Don't they lose sales because of libraries?Are libraries the bane of publishing companies?
Library sales help consumer sales.....readers are notorious for spreading the word that they enjoyed a book. Library readers tell their friends , friends buy books...

If publishing companies relied strictly on retail sales, many books wouldn't sell at all...

i balk at buying certain authors, however borrowing a book from the library is free, so i might take a chance....if i like it i tell my friends, if i like it enough, i might buy it , even though i've already read it....Are libraries the bane of publishing companies?
While it may be technically true that publishing companies lose some sales due to libraries (perhaps on big bestsellers and whatnot), but a decent amount of publishing revenues actually come from library sales. When I worked for a publishing company, there was little better than getting a good review in Library Journal, because we wanted the sales it would generate from library systems. I also think that even publishing companies can see the good that comes from libraries being able to provide literature for people. They don't make enough of an impact to be a threat.Are libraries the bane of publishing companies?
I have been to the American Library Association Conventions. The book publishers are definitely courting librarians. Libraries are a big source of revenue for them.
