4. Reuse of HKLII data by other commercial and non-commercial systems
(a) HKLII will not act as a data repository or supplier of source documents that it has obtained from their original sources, to other publishers for republication. This applies to both active re-supply of documents, or passive re-supply via spidering or other automated collection. Where spidering or other automated collection for these purposes is apparent, it will be blocked.
(b) HKLII does in some cases negotiate agreements with other publishers for them to frame HKLII pages as part of their services, including assisting them to identify the correct pages on HKLII to which to link.
