Fundamentals of Aerospace Engineering is licensed under a Creative Commons BY-SA 3.0 License, and it is offered in open access in “pdf ” format. This licensing is aligned with a philosophy of sharing and spreading knowledge.
You are free to copy, distribute, and publicly communicate this creation as long as*:
BY- You give credit to the author and editor in the terms herein specified.
SA- You license your derivative creations under the identical terms.
* Some of these conditions might not apply if you obtain explicit authorization by the owner of the rights. Notice also that this license applies to all contents except when explicitly licensed under other licenses as it is the case for those passages based on Wikipedia sources and some figures (licensed under public domain).
Creative Commons (CC) is a non-profit organization headquartered in Mountain View, California, United States, devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators. An easy-to-understand one-page explanation of rights, with associated visual symbols, explains the specifics of each Creative Commons license. Creative Commons licenses do not replace copyright, but are based upon it. They replace individual negotiations for specific rights between copyright owner (licensor) and licensee, which are necessary under an “all rights reserved” copyright management, with a “some rights reserved” management employing standardized licenses for re-use cases where no commercial compensation is sought by the copyright owner. The result is an agile, low-overhead and low-cost copyright-management regime, profiting both copyright owners and licensees. Wikipedia uses one of these licenses.
Creative Commons licenses consist of four major condition modules: Attribution (BY), requiring attribution to the original author; Share Alike (SA), allowing derivative works under the same or a similar license (later or jurisdiction version); Non-Commercial (NC), requiring the work is not used for commercial purposes; and No Derivative Works (ND), allowing only the original work, without derivatives. These modules are combined to currently form six major licenses of the Creative Commons:
Attribution (CC BY)
Attribution Share Alike (CC BY-SA)
Attribution No Derivatives (CC BY-ND)
Attribution Non-Commercial (CC BY-NC)
Attribution Non-Commercial Share Alike (CC BY-NC-SA)
Attribution Non-Commercial No Derivatives (CC BY-NC-ND)
As of the current versions, all Creative Commons licenses allow the “core right” to redistribute a work for non-commercial purposes without modification. The NC and ND options will make a work non-free according to the Definition of Free Cultural Works. An additional special license-like contract is the CC0 option, or “No Rights Reserved.” This license dedicates a work to the public domain (or an equivalent status in jurisdictions where a dedication to public domain is not possible). Compared with a “public domain” statement added to the work, a CC0 statement is less ambiguous and achieves the desired effect on a global scale, rather than limited to some jurisdictions.
