+Usage Guidelines and Requirements
+=================================
+
+Frequency, Timing, and Registration of E-utility URL Requests
+-------------------------------------------------------------
+
+In order not to overload the E-utility servers, NCBI recommends that users
+limit large jobs to either weekends or between 9:00 PM and 5:00 AM Eastern time
+during weekdays. Failure to comply with this policy may result in an IP address
+being blocked from accessing NCBI.
+
+Minimizing the Number of Requests
+---------------------------------
+
+If a task requires searching for and/or downloading a large number of
+records, it is much more efficient to use the Entrez History to upload
+and/or retrieve these records in batches rather than using separate
+requests for each record. Please refer to Application 3 in Chapter 3
+for an example. Many thousands of IDs can be uploaded using a single
+EPost request, and several hundred records can be downloaded using one
+EFetch request.
+
+
+Disclaimer and Copyright Issues
+-------------------------------
+
+In accordance with requirements of NCBI's E-Utilities, we must provide
+the following disclaimer:
+
+Please note that abstracts in PubMed may incorporate material that may
+be protected by U.S. and foreign copyright laws. All persons
+reproducing, redistributing, or making commercial use of this
+information are expected to adhere to the terms and conditions asserted
+by the copyright holder. Transmission or reproduction of protected
+items beyond that allowed by fair use (PDF) as defined in the copyright
+laws requires the written permission of the copyright owners. NLM
+provides no legal advice concerning distribution of copyrighted
+materials. Please consult your legal counsel. If you wish to do a large
+data mining project on PubMed data, you can enter into a licensing
+agreement and lease the data for free from NLM. For more information on
+this please see `https://www.nlm.nih.gov/databases/download/data_distrib_main.html <https://www.nlm.nih.gov/databases/download/data_distrib_main.html>`__
