Prior content in this article duplicated one or more previously published sources. The material was copied from: http://www.library.hbs.edu/hc/lehman/chrono.html?company=allentown_portland_cement_co. Infringing material has been rewritten or removed and must not be restored, unless it is duly released under a compatible license. (For more information, please see "using copyrighted works from others" if you are not the copyright holder of this material, or "donating copyrighted materials" if you are.) For legal reasons, we cannot accept copyrighted text or images borrowed from other web sites or published material; such additions will be deleted. Contributors may use copyrighted publications as a source of information, but not as a source of sentences or phrases. Accordingly, the material may be rewritten, but only if it does not infringe on the copyright of the original or plagiarize from that source.

While facts are not copyrightable, creative elements of presentation - including both structure and language - are. The less creative the expression, the looser copyright applies, but even so close paraphrasing becomes a great concern when there are long passages that include fragments of the original and the structure of the original is retained. The essay Close paraphrasing contains some suggestions for rewriting that may help avoid these issues. The article Wikipedia Signpost/2009-04-13/Dispatches, while about plagiarism rather than copyright concerns, also contains some suggestions for reusing material from sources that may be helpful, beginning under "Avoiding plagiarism".

Please see our guideline on non-free text for how to properly implement limited quotations of copyrighted text. Wikipedia takes copyright violations very seriously, and persistent violators will be blocked from editing. While we appreciate contributions, we must require all contributors to understand and comply with these policies. Thank you. VernoWhitney (talk) 14:47, 4 February 2011 (UTC)
