Sensei's Library does not claim ownership of the material, nor does it take responsibilty for it. You keep all rights to your material.
By submitting material to Sensei's Library you grant everyone the rights to copy, distribute, and modify the material under the terms of the Open Content License.
If you are considering to submit material of which you are not the original author, or material which is derived from such work, please bear the following points in mind:
- If you have reason to believe that the original author(s) would object to quotations of their work being published on SL, then do not publish it until they have given permission. If permission is not given, or if you do not try to obtain this permission, do not publish the material on SL.
- For original authors: If your material has been posted here and you do not agree with this, send an email to Arno or Morten, and it will be removed.
- Always attribute material to the original authors. If known, mention the source as well.
- There are many volunteers in the Go world, and the results of their efforts may not always be copyrighted material - but please apply the above.
- If the copied/quoted material outweighs your own contribution or if it is of minor interest to visitors of SL (e.g material unrelated to Go), even if you think that you have the legal right (e.g. due to fair use) the material may not be suitable for publishing here.
If you are confused as to the meaning of 'fair use' or the issue of copyright, take a look at these common misconceptions of copyright issues.
Internet copyright issues are complex and differ across jurisdictions. SL aims at being a good netizen and tries to take a stand which is reasonable and acceptable to all parties.
This page cannot be edited. Discuss it at /Discussion instead. However, please note that SL is not a good setting for, and its contributors are likely not qualified for, discussions based on legal merits alone.
From the OpenContent web site at http://opencontent.org/
OpenContent's only excuse for existing is to "facilitate the prolific creation of freely available, high-quality, well-maintained Content." This Content can then be used in an infinity of ways, restricted only by the imagination of the user. One of the most significant uses may be supporting instruction and helping people learn. [...]
[...] In plain English, the license relieves the author of any liability or implication of warranty, grants others permission to use the Content in whole or in part, and insures that the original author will be properly credited when Content is used. It also grants others permission to modify and redistribute the Content if they clearly mark what changes have been made, when they were made, and who made them. Finally, the license insures that if someone else bases a work on OpenContent, that the resultant work will be made available as OpenContent as well.
Version 1.0, July 14, 1998.
This document outlines the principles underlying the OpenContent (OC) movement and may be redistributed provided it remains unaltered. For legal purposes, this document is the license under which OpenContent is made available for use.

Terms and Conditions for Copying, Distributing, and Modifying
Items other than copying, distributing, and modifying the Content with which this license was distributed (such as using, etc.) are outside the scope of this license.
1. You may copy and distribute exact replicas of the OpenContent (OC) as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the OC a copy of this License along with the OC. You may at your option charge a fee for the media and/or handling involved in creating a unique copy of the OC for use offline, you may at your option offer instructional support for the OC in exchange for a fee, or you may at your option offer warranty in exchange for a fee. You may not charge a fee for the OC itself. You may not charge a fee for the sole service of providing access to and/or use of the OC via a network (e.g. the Internet), whether it be via the world wide web, FTP, or any other method.
2. You may modify your copy or copies of the OpenContent or any portion of it, thus forming works based on the Content, and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified content to carry prominent notices stating that you changed it, the exact nature and content of the changes, and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the OC or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License, unless otherwise permitted under applicable Fair Use law.
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the OC, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the OC, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Exceptions are made to this requirement to release modified works free of charge under this license only in compliance with Fair Use law where applicable.
3. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to copy, distribute or modify the OC. These actions are prohibited by law if you do not accept this License. Therefore, by distributing or translating the OC, or by deriving works herefrom, you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or translating the OC.
4. BECAUSE THE OPENCONTENT (OC) IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE OC, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE OC "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK OF USE OF THE OC IS WITH YOU. SHOULD THE OC PROVE FAULTY, INACCURATE, OR OTHERWISE UNACCEPTABLE YOU ASSUME THE COST OF ALL NECESSARY REPAIR OR CORRECTION.
5. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MIRROR AND/OR REDISTRIBUTE THE OC AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE OC, EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
