Many countries that are bound by one or another of these agreements have now incorporated into their national laws prohibitions on circumvention of TPMs. The terms of those provisions vary widely -- especially with regard to the penalties they impose on violators and with regard to exceptions they recognize. Currently, 26 countries have provisions specifically exempting libraries from liability if they circumvent TPMs in specified circumstances. In other countries, librarians are forced to rely upon more general exemptions.

TPMS and the anti-circumvention rules that reinforce them have many disadvantages, both from the standpoint of libraries and from the standpoint of society at large:

  • They prevent many activities that copyright law would permit. As a result, they frustrate the important social policies that lie behind the exceptions and limitations discussed in  Module 4
  • Because TPMs are often proprietary, they impede the interoperability of creative works and consumer electronic products obtained from different sources
  • When the technologies in which they are embedded become obsolete, they frustrate users' ability to gain access to the protected works

More extensive discussion of TPMs and the hazards they pose to libraries may be found in the  eIFL Handbook on Copyright and Related Issues for Libraries .

Orphan works

Sometimes a licensee would like to obtain a license to a particular work but cannot locate the copyright holder. This may occur for various reasons. The name of the author may be missing from the document. The document may have been published anonymously. The author may have died and the person who inherited his or her rights may be unknown. Or the author may have assigned his or her rights to a publisher, which later went out of business without a clear successor. In such situations, the work is said to be an  orphan work .

A small number of countries have implemented systems that make it possible to make use of orphan works. For example, in Canada, those who wish to use such works must apply to the Copyright Board for a license. Such applicants must first show that a reasonable effort to locate the copyright holder has been fruitless. If the work had previously been published, the Copyright Board will then grant the applicant a non-exclusive license (effective only within Canada) to use the work. The license is limited to particular types of uses, and requires the applicant to pay a designated royalty fee. This royalty can be claimed by the copyright holder for up to five years after the transaction, in the event that she later comes forth.

The Nordic countries of Denmark, Finland, Iceland, Norway, and Sweden have also enacted statutes governing the licensing of orphan works. In Denmark, for example, the licensing of orphan works is arranged through a collective management organization. The Danish Copyright Act provides that an individual interested in using an orphan work may arrange to pay a rights management organization for that use, provided that the organization represents a “substantial number” of Danish copyright holders. The royalties paid to these organizations may be claimed by a copyright holder for up to five years, and unclaimed royalties for orphan works are donated to public works programs.
