Charging for access to books in any format is antithetical to the purpose of libraries. Buying print versions of the many books that James Patterson, David Baldacci, and other author machines churn out multiple times a year costs an arm and a leg too, but we get them because they’re popular. Libraries wouldn’t get e-content at all if there weren’t demand for them, so we’re kinda stuck. Some people prefer them for good reasons: easier for traveling, searchable, text enlargement, etc. I’m not one of those people but I support them regardless.
