When you use electronic information resources such as licensed databases and electronic journals, comply with the copyright law and terms of use strictly.

  Most distributors decide their own usage policy.
  Please be aware that they generally prohibit the following uses:

  • Large-scale downloading that is indistinguishable from non-individual use
  • Use for any purpose other than academic research and education
  • Reproduction and distribution to others
  • Any other activities that infringes on the copyright law

  If you do not comply with these terms and conditions, it may result in loss of access to these resources for the entire Tokyo Tech community.

Terms of Use

  There are variations in each distributor's terms of use.
  However, these things below are prohibited by almost all distributors.
  If you need detailed information, please refer to their websites.

  1. Systematic or excessive downloading
  2.   It is prohibited to download a lot of files continuously using automated downloading software.
      Even if you download manually, it shall be considered as excessive use if you download a lot of files at one time.
      Please download only the needed volume of files.

  3. Use for any purpose other than academic research and education.
  4.   Use for any purpose other than academic research and education is not allowed.

  6.   Most electronic resources are governed by license agreements which restrict the use to Tokyo Tech faculty, students, staff and other authorized users.


  Q. What do distributors consider as "excessive downloading" ?

    A.  Here are several examples:
    • Downloading entire issues or volumes of an e-journal.
    • Rapidly or continuously downloading one article after another.
    • Using robots, spiders, or other automated downloading programs or devices.

  Q.  What happens if the License is violated ?

    A.  In most cases, the distributor will notify the library with details of violations and we are supposed to investigate in order to be able to request restoration. Meanwhile, the distributor also suspends access to their electronic resources.
        Access is stopped not only for journals where the licence agreement was violated, but for all journals by the same publisher. Moreover, access is suspended not only for the individual violator, but for the entire institution.

  Q.  Are there any cases of violation in the past ?

    A.  Yes:
    1.   A laboratory accessed an electronic journal and was continuously viewing full text articles.
        After 1 hour, they suddenly couldn't access the resources. They were just displaying the articles, but the distributor counted it as downloading.
        They accessed via the proxy server provided by the Network Operation Center (NOC), so others who also used the proxy server couldn't access the resources either.
    2.   A laboratory enabled the "Save Tabs" option of their web browser, and someone closed a window with tabs left open.
        When they reopened the browser every tab, which included the PDF files of electronic journals, reopened automatically. The distributor counted it as downloading, and access to that resource was cut off.

  Please be aware that publishers may monitor the use of electronic resources to ensure that the terms of the license agreement are enforced.
