Main Content

Several classes of materials may not be available through normal interlibrary loan sources. Some of these items may be unique and available only from a single source. Please read the appropriate section if you are requesting materials in the following classes:

  • Center for Research Libraries materials

    The Virginia Tech Libraries is one of 230 members of the Center for Research Libraries (CRL). CRL acquires and preserves newspapers, journals, documents, archives and other traditional and digital resources for research and teaching. These resources are then made available to member institutions through interlibrary loan and electronic delivery. Use Virginia Tech Interlibrary Loan ILLiad to submit requests.

  • Dissertations and theses

    It is becoming increasingly difficult to know in advance whether it will be possible to borrow a particular thesis or dissertation from a particular university through interlibrary loan. Most universities will lend a paper copy of a masters thesis or Ph.D. dissertation if a paper copy is available. However, some universities will not lend paper copies at all. Even those universities that will lend paper copies may not have paper copies after a particular date, and only an electronic copy may exist. Whether you will be able to access that electronic copy varies according to the policies of the individual university. Some electronic copies may be available through the Web, others may not.

  • ERIC documents

    The Education Resources Information Center (ERIC), sponsored by the U.S. Department of Education, produces the world’s premier database of journal and non-journal education literature. The ERIC online system provides the public with a centralized ERIC Web site for searching the ERIC bibliographic database of more than 1.2 million citations going back to 1966. More than 107,000 full-text non-journal documents issued 1993-present are freely available in the ERIC from the U.S. Department of Education .

  • Media materials (Educational/Research)

    Requests for media materials (videos, DVDs, compact discs, etc.) should be for educational/research purposes. Any questions or concerns can be directed to Sharon Gotkiewicz at 540-231-9202.

    All media materials are subject to the copyright law of the United States (Title 17, United States Code) and must comply with federal copyright law and other applicable state and federal laws in regards to duplication, exhibition, and distribution.

  • NTIS reports

    You can obtain NTIS (National Technical Information Service) reports through ILLiad. See the NTIS Web page for more information about the NTIS report collections and NTIS services. Phone numbers for the NTIS orders desk are on the NTIS Ordering Information page.

  • Patents

    All United States patents issued since 1790 are available as full page images directly from the U. S. Patent and Trademark Office (USPTO) Web Patent Database. Patents issued since 1976 are also available as full-text HTML pages.

    The European Patent Office provides access to a variety of Patent Information Products and Search Engines. 

    • esp@cenet is a gateway to patent indexes, with support for several languages when accessed through the national offices of member states
    • English, German, and French interfaces are available on the European Patent Office's Patent Databases page. 
    • Included are patents from the European Patent Office, the World Intellectual Property Organization, and from world-wide sources including the United States and Japan.
  • SAE Technical Papers

    All SAE Technical Papers are now requested through ILLiad. You will receive a PDF of the paper. Please include the SAE paper number and the title of the SAE paper in your request so that we can correctly identify the paper you are requesting.

  • Standards

    Industry standards are not usually available on loan from other libraries. Instead, they must be purchased from the organization that issues the standard, or from a commercial document supplier that specializes in acquiring standards.

    You can find this information about the standard you need by searching the standards database maintained by IHS/Global, the world's leading distributor of standards and other technical documents. See also our guide to finding standards.
