I said it once in a roomful of librarians and their collective gasp almost sucked in the windows. Information is not free. We may not charge for it, but there are definitely costs involved. We have costs associated with processing and maintaining our collection and equipment, overhead, staff time, and paper and other supplies we use for ourselves or our patrons. It doesn't really matter what the product is worth to us.
Price is often a measure of quality.
You get what you pay for. Next we need to consider how people will access our product. We need to consider how our library appears from the users' point of view and organize it accordingly. Then we look at our channels of distribution. When we get to this step we should know what we have and who we want to reach.
