Content and Specifications
CCRIS, ChemIDplus Subset, DIRLINE®, GENE-TOX, HSDB®, and TOXLINE® Subset
Click on each database name above for a description of that database. All are available for distribution in XML format via ftp.

Special note for ChemIDplus Subset: ChemIDplus structure and toxicity data available online at NLM are not available for distribution to licensees, nor does it include data with the source tag of USPDDN available in the web versions of ChemIDplus. Contact Jeff Spencer (JFS@usp.org) of the U.S. Pharmacopeial Convention, Inc., the provider of USPDDN data for ChemIDplus, for information about leasing USPDDN data directly from USP.

Special note for TOXLINE Subset: Restrictions apply to the IPA archival subfile (NLM does not currently add IPA data to TOXLINE Subset). The American Society of Health-System Pharmacists (ASHP), the producer of IPA, requires a special arrangement with NLM's licensees before NLM may distribute IPA data. TOXLINE Subset licensees who wish to obtain this subfile from NLM should contact ASHP (http://www.ashp.org; telephone: 301.657.3000). Any exception to the restrictions will be made by the data supplier. If you wish to receive IPA data, you should inform NLM that your arrangements have been made when the license paperwork is first submitted and when a new Intended Use Worksheet is submitted each subsequent year.

Sample NLM Data
Sample data is available for prospective NLM data licensees. A license agreement is not needed for sample data.

How to Lease
NLM leases CCRIS, ChemIDplus Subset, DIRLINE®, GENE-TOX, HSDB® and TOXLINE® Subset to U.S. individuals or organizations; to its formally recognized International MEDLARS Centers; and to non-U.S. individuals or organizations solely for research purposes (limited to internal use with no commercial applications). For purposes of leasing NLM databases, the following criteria must be met to be considered a U.S. organization: the organization is incorporated in the U.S.; the signing official is a principal in the organization who is located in the U.S. and is not simply an authorized agent; and any financial payment to the NLM is issued from an U.S. account (although there are no fees for leasing NLM databases in the foreseeable future).

To lease, complete and return the applicable License Agreement and the Intended Use Worksheet.

Obtain NLM's usage report form at http://www.nlm.nih.gov/databases/license/userep.html for submission at the end of the U.S. Federal Government fiscal year, i.e., after September 30.
