This page provides information about copyright restrictions that apply to content in Bookshelf.

Non-government publications

Content in Bookshelf which is provided by non-government authors and publishers is copyright protected and usually includes an explicit copyright statement. In the absence of a copyright statement, users should assume that standard copyright protection applies, unless the book contains an explicit statement to the contrary. In case of doubt, contact the publisher to verify the copyright status of a publication.

Where available, links to specific copyright statements are provided in the section, Publisher-specified Copyright Statements. Please contact the respective copyright holder to obtain permission before reproducing any material found in such publications. Such content can be identified by the presence of the copyright symbol (©).

Some of the content found in the Bookshelf is still protected by copyright, but is made available under a Creative Commons or similar license that generally allows more liberal redistribution and reuse than a traditional copyrighted work. Please refer to the license statement in each publication for specific terms of use. The license terms are not identical for all open access publications.

Publications in the Public Domain

Some of the content found in Bookshelf is authored and published by the National Center for Biotechnology Information (NCBI) or other institution of the U.S. government. No permission is needed to reproduce or distribute this type of content, as it is in the public domain. It is requested, however, that if this content is to be reproduced or distributed, the authoring institute or agency be given appropriate acknowledgement.

Occasionally, copyrighted material (such as a figure, table, or block of text), may appear in a U.S. government publication in Bookshelf. In these cases, a special copyright statement such as “Reprinted with permission from…” will accompany the material. Permission must still be sought from the original author/publisher of such material before it can be reproduced or distributed.

Restrictions on Systematic Downloading of Books or Chapters

Crawlers and other automated processes may NOT be used to systematically retrieve content from the Bookshelf web site and bulk downloading of books is prohibited.
