                        Open Publication License
    Draft v1.0, 8 June 1999 (text version) 
    The Open Publication works may be reproduced and distributed in whole or
    in part, in any medium physical or electronic, provided that the terms 
    of this license are adhered to, and that this license or an 
    incorporation of it by reference (with any options elected by the 
    author(s) and/or publisher) is displayed in the reproduction. 
    Proper form for an incorporation by reference is as follows: 
        Copyright (c) 2001 by Thomas Nesges. This 
        material may be distributed only subject to the terms and 
        conditions set forth in the Open Publication License, v1.0
        or later (the latest version is presently available at 
    The reference must be immediately followed with any options elected by 
    the author(s) and/or publisher of the document (see section VI). 
    Commercial redistribution of Open Publication-licensed material is 
    Any publication in standard (paper) book form shall require the citation
    of the original publisher and author. The publisher and author's names 
    shall appear on all outer surfaces of the book. On all outer surfaces of
    the book the original publisher's name shall be as large as the title of 
    the work and cited as possessive with respect to the title. 
    The copyright to each Open Publication is owned by its author(s) or 
    The following license terms apply to all Open Publication works, unless 
    otherwise explicitly stated in the document. 
    Mere aggregation of Open Publication works or a portion of an Open 
    Publication work with other works or programs on the same media shall 
    not cause this license to apply to those other works. The aggregate work 
    shall contain a notice specifying the inclusion of the Open Publication 
    material and appropriate copyright notice. 
    SEVERABILITY. If any part of this license is found to be unenforceable 
    in any jurisdiction, the remaining portions of the license remain in 
    NO WARRANTY. Open Publication works are licensed and provided "as is" 
    without warranty of any kind, express or implied, including, but not 
    limited to, the implied warranties of merchantability and fitness for a 
    particular purpose or a warranty of non-infringement. 
    All modified versions of documents covered by this license, including 
    translations, anthologies, compilations and partial documents, must 
    meet the following requirements: 
    * The modified version must be labeled as such. 
    * The person making the modifications must be identified and the 
      modifications dated. 
    * Acknowledgement of the original author and publisher if applicable 
      must be retained according to normal academic citation practices. 
    * The location of the original unmodified document must be identified. 
    * The original author's (or authors') name(s) may not be used to assert 
      or imply endorsement of the resulting document without the original 
      author's (or authors') permission. 
    In addition to the requirements of this license, it is requested from 
    and strongly recommended of redistributors that: 
    * If you are distributing Open Publication works on hardcopy or CD-ROM, 
      you provide email notification to the authors of your intent to 
      redistribute at least thirty days before your manuscript or media 
      freeze, to give the authors time to provide updated documents. This 
      notification should describe modifications, if any, made to the 
    * All substantive modifications (including deletions) be either clearly 
      marked up in the document or else described in an attachment to the 
    * Finally, while it is not mandatory under this license, it is 
      considered good form to offer a free copy of any hardcopy and CD-ROM 
      expression of an Open Publication-licensed work to its author(s). 
    The author(s) and/or publisher of an Open Publication-licensed document 
    may elect certain options by appending language to the reference to or 
    copy of the license. These options are considered part of the license 
    instance and must be included with the license (or its incorporation by 
    reference) in derived works. 
    A. To prohibit distribution of substantively modified versions without 
    the explicit permission of the author(s). "Substantive modification" is 
    defined as a change to the semantic content of the document, and 
    excludes mere changes in format or typographical corrections. 
    To accomplish this, add the phrase `Distribution of substantively 
    modified versions of this document is prohibited without the explicit 
    permission of the copyright holder.' to the license reference or copy. 
    B. To prohibit any publication of this work or derivative works in whole 
    or in part in standard (paper) book form for commercial purposes is 
    prohibited unless prior permission is obtained from the copyright 
    To accomplish this, add the phrase 'Distribution of the work or 
    derivative of the work in any standard (paper) book form is prohibited 
    unless prior permission is obtained from the copyright holder.' to the 
    license reference or copy.
