The ABC Global Book Service, formerly known as the TIGAR Service, is an on-line catalogue that allows participating libraries for the blind and organizations serving people who are print disabled, known as authorized entities, to obtain easily the accessible content they need. The Service supports the goals of the Marrakesh VIP Treaty at a practical level.
A participating authorized entity contributes its catalogue and may request accessible digital books contributed by other organizations for the purpose of supplementing its collection and distributing to people who are blind, visually impaired or otherwise print disabled.
- In those countries that have ratified and implemented the provisions of the Marrakesh VIP Treaty, such books can be exchanged across borders between participating authorized entities without requesting authorization from the copyright owner.
- For those countries that have not, ABC seeks authorization from the copyright owner prior to the exchange across borders.
