Important Notice: In addition to our official mirrors and foreign-language sites listed above, an increasing number of "unofficial" mirrors and more or less modified or derived copied websites seems to be around. In some cases, not even hints are given to that they got their materials from us. Up to here, we don't really care about this practice at this time, although we would appreciate it to get notified by the maintainers of these "mirrors" and "derived sites" - they all are invited to become official mirror sites (see above, or submit the relevant data).

Recently, a small but unfortunately increasing number of sites have started to claim false copyrights on stuff originating or obtained from us. We strongly deprecate this practise, state that it is unlawful to claim inappropriate rights on stuff originating from our services (see our usage regulations page), and particularly emphasize that this might cause third-party royalty holders, or at some time even ourselves, to bring serious problems to those falsely claiming any ownership rights on their (the owners') stuff. Concerned parties are requested to remove any false claims of rights.
