B. *DECLARATION FOR GOVERNMENT WORK (See ACM Copyright Procedures below)
Note: Co-authors of government employees and subcontractors of the U.S. Government are also required to sign
in Part A. A modified copyright statement regarding government use will appear on the published work.

C. Third-Party Material (See Policy, Sec. 2.1 Requirement for Copyright)
This copyright transfer applies only to the work as a whole, not to any embedded objects owned by third
parties. An author who embeds third-party art images, figures, tables, charts, graphs, photos, music, slides
or passages of text that they did not originate, must obtain the owner’s permission to include the material,
with the understanding that the entire work may be distributed as a unit in any medium.
The requirement to obtain permission does not apply if the author embeds only a link to the third-party’s
definitive version of the object. Quotations of text less than 50 words are usually considered a “fair use”
which does not require third-party permission. Third-party citations and permission must be clearly
stated near the object(s) or in the text narrative.
Indicate below any third-party material included in this submission (ACM Reference), describe or cite the
third-party material (Original Citation) and attach the copyright owner's dated permission or a rationale for
a claim of Fair Use. Use a separate sheet if additional space is needed.

TO: Authors Submitting Papers for Publication by ACM
FROM: ACM Director of Publications
SUBJECT: ACM Copyright Procedures
Thank you for submitting a paper for publication by ACM, Inc. ACM's publications are read throughout the world
and we must manage requests for reprinting, republishing, redistributing, digitizing, posting to servers, translating,
anthologizing, and other actions. It is the policy of ACM to own the copyright on its technical publications to
protect the interests of ACM, its authors and their employers, and at the same time to facilitate the appropriate reuse
of this material by others.
United States Copyright Law requires that the transfer of copyright of each contribution from the author to ACM be
confirmed in writing. (See ACM Copyright Policy, Sections 2.1 and 2.2) It is necessary that authors sign either
Part A or Part B of the ACM Copyright Form and return it with the manuscript to the publication's editor at the
address on the Form, unless otherwise noted, as a condition of publication.
If you are employed and prepared your paper as part of your job, the rights to your paper may initially rest with your
employer. In that case, when you sign the ACM Copyright Transfer Form, we assume that you are authorized to do
so by your employer. If not, the Form should be signed by an authorized person.
For jointly authored papers, an original signature is required from one (assumed senior) author only. However, we
assume that all authors have been advised and have consented to the terms of this Form and this single author acts as
duly authorized agent of the others.
*Government employees who prepared the work as part of their job, and whose work is not subject to copyright,
are not required to sign Part A, but all co-authors outside the Government are so required. Use Part B of the
Form instead of Part A only if any or all authors are Government employees, or the work was performed exclusively
for a Government agency.
In the case of a Work performed under a Government contract or grant, ACM recognizes that the Government
has royalty-free permission to reproduce all or portions of the Work, and to authorize others to do so, for official
Government purposes only, if the contract/grant so requires. Authors employed by a civilian agency working under
Government contract are required to sign in both Parts A and B. (See Part B above.)
ACM authors have all the rights historically enjoyed by scientific authors, including the right to present orally the
submitted (or similar) material in any form or media and the right to republish in works published by or for the
employer for the employer's internal business purposes, with notice and credit to ACM. They retain all proprietary
rights other than copyright. (See ACM Copyright Policy, Sections 2.4, 2.5 and the Permissions Policy, Sec. 3).
ACM Authors may post works on public repositories before acceptance but must incorporate the ACM
copyright notice upon transfer of copyright. After acceptance, authors may post the work on public
repositories only with the explicit permission of ACM.
Re-use of third-party material contained in ACM copyrighted works always requires the consent of the copyright
holder, as ACM's copyright does not cover third-party material. (See Part C above.)
Note: **Requests made on behalf of others, i.e., for contributions to the work of other authors or other editors, may
require payment of the fee.
Although it is not part of ACM's policy to grant authors or their organizations the sole right to approve requests for
republishing by third parties, ACM seeks the approval of its authors, for jointly authored papers the first-named
(assumed senior) author only, in weighing such requests, whenever possible. This is done as a matter of professional
