ETDE Leading the Way to WorldWide Energy Technology Discoveries

 

ETDE

Information Sources

ETDE's Energy Database is built through a myriad of collaborative efforts. The Partners section of the website has links to many of the organizations involved. Member countries bear the primary responsibility for input to the database. Their efforts include expending resources to acquire/locate documents published within their borders that are within the subject scope of the database, translation (if necessary), cataloging records bibliographically, providing abstracts and subject indexing, and ensuring an availability source, including the provision of electronic full text when possible. Each member may have a number of partnerships in place with other organizations/publishers within their country to facilitate this process.

In addition to member input, the database also benefits from the inclusion of information from two other large international information sources in specific subject areas. The International Atomic Energy Agency's International Nuclear Information System (INIS) is a multilateral information exchange agreement which focuses on the peaceful uses of nuclear energy. As all members of ETDE are also members of INIS, most INIS information is also included in the ETDE database. The IEA Clean Coal Centre's (IEACCC) Coal Abstracts database focus is, naturally, in the coal area of the energy field. Per a long-standing memorandum of understanding with ETDE, much of IEACCC’s information is also cited in the ETDE database. IEACCC’s decision to cease updating Coal Abstracts in 2011 also impacts ETDE’s database content in the coal area. Some of the major IEACCC research reports may continue to be cited.

The following table provides information about how many records enter the database that are published in member countries, plus how many database additions are included from non-members via ETDE's partners. The most recent calendar year numbers are provided. Each quarter of the current calendar year will be added as the data becomes available.

*Non-member input. **Input from source has ceased being tallied separately. 
†Changes in the processing stream resulted in some database input not being processed until 2013.

ETDE strives to include publications generated from its parent organization, the IEA, and from the various other IEA Implementing Agreements. While ETDE has been successful in covering those from the IEA, additional help is needed in finding out about publications generated from the other agreements. Please contact the ETDE Operating Agent if you are aware of key publications not already in the database.
