Caution for Systematic Download

Systematic downloading of electronic resources are strictly prohibited.

For example you must not:
  • Downloading with programs: "crawlers", "robots", "spiders" etc...
  • Downloading with download support softwares
  • Downloading all volumes or all articles of an specific journal 
  • Rapidly downloading one article after another

When a lot of download requests are send from one specific computer within a given period , it may be regarded as "Systematic Download" even if it is manually done.
The standard of allowable downloading depends on publishers or associations.

Please be aware that systematic downloading will cause the publisher to block entire community of users of University of Tsukuba from accessing our subscribed resources.

Use Caution for Link Prefetching Function of Web Browser

While electronic journals or databases are used, several cases are reported where, owing to link prefetching function of web browser, repeated access to the link within the webpage in the background unintendedly lead to systematic download.
Please cancel link prefetching function of your web browser according to the following steps. Many cases are reported with Microsoft Edge users in particular.

  • Microsoft Edge
    Click “Settings” > “View advanced settings”, then use the slide to cancel “Use page prediction to speed up browsing, improve reading, and make my overall experience better”.
  • Internet Explorer 11
    Click “Tools” > “Internet Options” > “Advanced” tab, then uncheck “Load sites and content in the background to optimize performance”.
  • Google Chrome
    Click “Settings”>”Privacy and security”, then uncheck “Preload pages for faster browsing and searching”.
  • FireFox
    Type “about:config” in Firefox URL bar and press Enter.
    If the confirmation message “This might void your warranty!” is appeared, click “I’ll be careful, I promise!”
    Double click “network.prefetch-next” and set to false.
  • Safari (Mac)
    Choose “Safari” > “Preferences”, then click “Search” and uncheck “Preload Top Hit in the background”.
