[Utilities-announce] NCBI Revised E-utility Usage Policy

[utilities-announce at ncbi.nlm.nih.gov]

New E-utility documentation now on the NCBI Bookshelf
The Entrez Programming Utilities<http://www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=helpeutils> (E-Utilities) Help documentation has been added to the NCBI Bookshelf, and so is now fully integrated with the Entrez search and retrieval system as a part of the Bookshelf database. This help document has been divided into chapters for better organization and includes several new sample Perl scripts. At present this book covers the standard URL interface for the E-utilties; material about the SOAP interface will be added soon and is still available at the same URL: http://eutils.ncbi.nlm.nih.gov/entrez/query/static/eutils_help.html.

Revised E-utility usage policy
In December, 2009 NCBI announced a change to the usage policy for the E-utilities that would require all requests to contain non-null values for both the &email and &tool parameters. After several consultations with our users and developers, we have decided to revise this policy change, and the revised policy is described in detail at the following link:

http://www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=helpeutils&part=chapter2#chapter2.Usage_Guidelines_and_Requiremen

Please let us know if you have any questions or concerns about this policy change.

Thank you,
