COPYRIGHTS AND LICENSES
This page specifies the copyrights,
licenses, and public domain
dedications of The Online Books Page. The statements here
are subject to the scope details at the bottom
of the page.
This site is edited by John Mark Ockerbloom, who began the site
in 1993. Versions of this site from 2003 through the present,
except for metadata described below, are copyright by John Mark Ockerbloom.
Contact the editor for permissions and questions on material not
covered by the public domain declarations below.
Extended Shelves Catalog Entries
Catalog data describing entries on our "extended shelves" has been
provided by HathiTrust,
the University of Florida Baldwin Library,
and the Directory of Open Access Journals.
We have modified some of their data with automated scripts
for better compatibility with this catalog.
Reuse of their data may be subject to their respective licensing terms.
(As of May 2016, Gutenberg's catalog is distributed under the
GNU General Public License, DOAJ's data is distributed under the
Creative Commons Attribution-ShareAlike license,
and I am not aware of restrictions being
placed on HathiTrust's bibliographic metadata. Follow the links above
to those projects for more details.)
Curated Collection Catalog Entries in the Public Domain
Catalog data describing entries in our "curated collection" has been
compiled by the editor, John Mark Ockerbloom, and his associates,
drawing in part on factual information provided by others. Any copyright
claims to this data are released to the public domain under the
Public Domain Dedication. The catalog pages in our curated collection
have a note about the public domain/CC0 status of their data.
(See, for instance, the note at the bottom of
this book listing.)

Old Versions of the site in the Public Domain
The copyrights for versions of this site from 1993 through 2003 are dedicated
to the public domain, as of January 1, 2018.
This is a complete, and irrevocable,
dedication of those copyrights.
This dedication is in honor of the founders of the United States
government, who originally specified a copyright term of 14 years,
optionally renewable for another 14. As I am an advocate of shorter
terms of copyright than exist today, I am happy to use those original terms
for this site (and forgo the "renewal term" in this case).
I intend to keep
dedicating an additional year's worth of copyrights of versions of this site
to the public domain at the start of every new year.
Pre-2003 versions of the site at its Carnegie Mellon and Penn locations can be found
at the Internet Archive's Wayback Machine.
The statements here apply to the pages and files of The Online Books Page
(as located at onlinebooks.library.upenn.edu, digital.library.upenn.edu,
and www.cs.cmu.edu) that are marked as edited or copyrighted by
John Ockerbloom or John Mark Ockerbloom, and that have a link
(or whose current versions have a link) to this page labeled
"OBP copyrights and licenses".
They do not apply to the books linked to from this site, which are
on other sites not under our control. The online books we list
may be copyrighted or in the public domain, and may have their own
status and permitted uses of any book we list, ask the maintainers
of the site that hosts the book, or consult the book's own copyright
statements or holders.
Also, the statements above do not apply to A Celebration of
Women Writers, which is edited and copyrighted separately
by Mary Mark Ockerbloom.
Licenses and public domain dedications above apply only to the copyrights
to this site. They do not apply to the names, service marks, or
other rights of attribution that are not included in copyright.
Which is basically a long-winded way of saying that, while you're
free to copy and modify this site as permitted by the statements above,
you're not free to call a modified version of The Online Books Page
"The Online Books Page", or use the site's logos, unless it's clear
that you've altered it from its original form and content (and are
otherwise abiding by the licenses above). Or, even
more concisely, don't make it look like we're responsible for
content we're not actually responsible for, or have endorsed things
that we have not endorsed.
Thanks for reading, and enjoy using and reusing the site!
