Yes recently we are observing growing concern of saving real Blogger’s writing. But traditional copyright is expensive, some copyright like copyscape offer low cost copyright and free too(limited). But we Blogger need something flexible yet F-R-E-E.

After a wide search I noticed Creative Commons(CC), it’s free. You can copyright your work for free-Video, Audio, Writing, Blog almost everything. They offer many categories of copyright like—

Attribution Non-commercial No Derivatives (by-nc-nd)

Choose by-nc-nd licenseThis license is the most restrictive of our six main licenses, allowing redistribution. This license is often called the “free advertising” license because it allows others to download your works and share them with others as long as they mention you and link back to you, but they can’t change them in any way or use them commercially.

Attribution Non-commercial Share Alike (by-nc-sa)

Choose by-nc-sa licenseThis license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms. Others can download and redistribute your work just like the by-nc-nd license, but they can also translate, make remixes, and produce new stories based on your work. All new work based on yours will carry the same license, so any derivatives will also be non-commercial in nature.

Attribution Non-commercial (by-nc)

Choose by-nc licenseThis license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.

Attribution Share Alike (by-sa)

Choose by-sa licenseThis license lets others remix, tweak, and build upon your work even for commercial reasons, as long as they credit you and license their new creations under the identical terms. This license is often compared to open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use.

Attribution (by)

Choose by licenseThis license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered, in terms of what others can do with your works licensed under Attribution.

Other licenses

They also offer a set of other licenses for more specialized applications. Sampling Licenses allow for snippets (not whole work) to be remixed into new works, even commercially. Our Public Domain Dedication lets you free works from copyright completely, and our Founders Copyright lets you do the same, but after 14 or 28 years. Musicians looking to share their work with fans might want to look at the Music Sharing license. The Developing Nations license lets you offer less restrictive terms to countries that aren’t considered high income by the World Bank, and finally, for those licensing software, they offer the GNU GPL and GNU LGPL licenses.
