About The Geothermal Technologies Legacy Collection

The Geothermal Technologies Legacy Collection is available to the geothermal community and interested members of the public who may use this site and its search and knowledge tools (learn about "Hot Docs", below) to stay better informed of developments in geothermal technology and to gain insights learned from studies in the field since the 1970s. By searching the Geothermal Technologies Legacy Collection, users can expect to find a wealth of geothermal citations and reports from various resources including the Department of Energy (DOE) and its national laboratories, industry within the United States, and similar organizations from around the world.

The overall geothermal collection at OSTI includes not only DOE-sponsored technical reports and conference proceedings or papers but also includes items such as United States and internationally published journal citations and patents for geothermal products and technologies.

Within the overall collection is a specially denoted* set of geothermal documents which are part of the Geothermal Legacy Collection. The legacy reports, many of which were electronically archived and made web searchable in 2006, are among the most valuable sources of DOE-sponsored information - historical and current - in the geothermal field. In addition to DOE reports, some geothermal legacy documents from other government or state agencies and organizations are included.

Using Basic Search or Advanced Search will focus your retrieval on documents from the geothermal collection (both overall and legacy) from the repository at U.S. DOE Office of Scientific and Technical Information (OSTI). A large number of these documents have been produced as the result of DOE sponsorship or funding.

Using the Distributed Search will find items available not only from OSTI (as above) but also from multiple databases residing at different agencies.

Hot Docs

A recent enhancement to the geothermal legacy site is "Hot Docs". These are documents that have been searched for and downloaded more than any other documents in the database during the previous month and each preceding month. "Hot Docs", another specially denoted** set of geothermal documents, are highlighted for researchers and stakeholders who may find it valuable to learn what is of interest to others in their field. This enhancement to the site could serve, for instance, to push and expand research knowledge as well as opportunity for partnerships.

There are a couple of ways to see "Hot Docs". One is by selecting the menu button on the home page, and throughout the site, which links to a browsable list of the "Hot Docs". Another way to get to "Hot Docs" is via the Advanced Search option. In this way, a user inputting his own query can discover "Hot Docs" when performing a search.

For example, when someone searches, a current "hot" topic such as "Enhanced geothermal systems" or EGS, the search results are likely to contain "Hot Docs".

The Geothermal Technologies Legacy Collection is sponsored by the DOE Energy Efficiency and Renewable Energy (EERE) Geothermal Technologies Program. In particular, content development for the Geothermal Legacy Collection has been provided by Leland L. (Roy) Mink (retired), Allan J. Jelacic, and Jay Nathwani, EERE Geothermal Technologies Program; Daniel J. Entingh, retired from Princeton Energy Resources International, LLC (PERI); Roland N. Horne, Professor of Petroleum Engineering, Stanford University; and geophysicist Bill Cumming, and others in the geothermal community. Technical assistance is provided by the OSTI.
