Open Publication License v1.0, 8 June 1999

I. REQUIREMENTS ON BOTH UNMODIFIED AND MODIFIED VERSIONS

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 © 1999-2013 by each contributor. 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
    http://www.opencontent.org/openpub/).

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 permitted.

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 bridgehead of the work and cited as
possessive with respect to the bridgehead.

II. COPYRIGHT

The copyright to each Open Publication is owned by its author(s) or designee.

III. SCOPE OF LICENSE

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 force.

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.

IV. REQUIREMENTS ON MODIFIED WORKS

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.

V. GOOD-PRACTICE RECOMMENDATIONS

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 document.

    All substantive modifications (including deletions) be either clearly marked
    up in the document or else described in an attachment to the document.

    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).

VI. LICENSE OPTIONS

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 holder.

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.  OPEN
