And this is why I don't use the term "open source" anymore. The "top 5 reasons to use open source" are all completely disconnected and don't really have any logical progression from the "ideals of open source" ("open source" doesn't have an ideology). Why libraries should use free software is a much more straightforward list:<p>1. Free software means that libraries can be assured that they can continue running on the same software and freely maintain it, without needing to worry about downgrades or license agreements.<p>2. Free software means that libraries can collaborate on improving the software they use (and help one another to run their libraries efficiently) without violating a proprietary license agreement.<p>3. Libraries are meant to be stewards of knowledge, and proprietary software takes away your ability to learn about software. Free software solves this problem, for the patrons as well as the librarians.<p>4. The reading history of an individual should remain private, and there is no way for a library to be sure of this without using free software. A reading history that can be used as evidence threatens human rights.<p>5. A library running on free software cannot ever be pressured by developers to stop distributing some form of book. As libraries are a primary source of information and knowledge, this is a freedom of speech issue and can only truly be solved by free software.<p>All of the above list clearly links to the four fundamental freedoms (with emphasis on my own politics). But that's why I invite everyone to refer to free software by it's proper name.
