Throughout our country's history, libraries have provided education and entertainment to all. In the library all economic classes have an equal opportunity to access information.
The movement to digital media has seriously disrupted this model. Content owners continue to exert more and more control over their works. No longer are they willing to sell "copies" to libraries. Some allow libraries to rent very restricted versions. Others refuse to deal with libraries at all.
We need to bring back the first sale doctrine for libraries, allowing them to copy and archive digital media without violating the DMCA.
Not doing so will ensure that only those with means have access to the wealth of human knowledge.
