[Library Network] Conditions of Use and Licensing Restrictions for E-Resource
Prohibited Actions When Using Electronic Resources
Mass Downloading Strictly Prohibited
- Automated operations or bulk downloads using programs
- Rapid consecutive clicks (prohibited even manually)
- Access via browser prefetch functions
- Copying, redistribution, or use beyond personal purposes
Cases of Unintentional "Excessive Access"
Cases where actions are considered "attacks" by system specifications are increasing, even without malicious intent.
Multiple people in a lab divided download tasks manually. Since the access source (university IP) was the same, it was detected as concentrated access in a short period.
Clicking through HTML abstracts and full texts one after another. Even without opening PDFs, the request frequency to the server was considered "downloading".
The "auto-import PDF" setting in reference management software was ON, causing repeated mass access in the background.
A book fell on the keyboard, holding down the F5 key (refresh). Hundreds of accesses were recorded in just a few minutes.
Essential! Settings Review Checklist

"Time Stamping" Feature Now Available on KURENAI
1. Overview
We are pleased to announce that starting from April 2026, KURENAI has introduced a time-stamping function using the Time Stamping Service provided by the National Institute of Informatics (NII), aimed at improving the reliability of published papers and data. With this feature, it is now possible to prove "when the content was registered" and "that it has not been modified since registration" for contents registered in KURENAI, allowing for the external demonstration of file integrity.
2. What is a Time Stamp?
A time stamp is an "electronic postmark" applied to digital files. Just as a physical postmark proves that a post office received a letter on a specific date, a time stamp proves that "this electronic file existed at this date and time and has not been changed since then."
A time stamp can prove the following two points:
- Proof of Existence: A third-party organization certifies that the content existed at the time of the postmark. Can be used to demonstrate research priority.
- Proof of Non-tampering: A third-party organization certifies that the content has not been altered at all from the time of the postmark to the present.
The third-party certification provided by KURENAI's "Time Stamping Function" utilizes the Time Stamping Service of the National Institute of Informatics. For more details, please see the following page.

[Library Network] Kyoto University Rare Materials Digital Archive : Important Cultural Property "Dainihonshi Hensan Kiroku" Vol.62-66 (G.S. Letters) Newly Released
The Graduate School of Letters of Kyoto University and the Kyoto University Museum have been carrying out the restoration and digitization of an important cultural property Dainihonshi hensan kiroku held by the Graduate School of Letters since academic year 2017. 202 images of the restored volumes 62-66 are now available in Kyoto University Rare Materials Digital Archive.
▼Important Cultural Property - Dainihonshi hensan kiroku (G.S. Letters)
Dainihonshi hensan kiroku (大日本史編纂記録) is a collection of more than 6,000 letters (copies) exchanged between Shokokan (彰考館; Mito Domain’s office for history compilation) in Mito (currently in Ibaraki Prefecture) and Edo (currently Tokyo) and their Kyoto office regarding the compilation of Dainihonshi by Tokugawa Mitsukuni (徳川光圀; 1628-1701). A total of 42,810 people and organizations and 15,159 historical records and literature works are mentioned in the letters and the content covers a wide range of aspects of the time, such as history, literature, Confucianism and Japanese classical literature, as well as the publishing culture during the Genroku Period, which makes this rare material a first-class historical record.
Therefore, a restoration project was launched in academic year 2017 funded by the Sumitomo Foundation (2017-2022), and also by government (2021-2023). The Graduate School of Letters has also set up Kyoto University Fund for the restoration of its library collection and the Kyoto University Museum acquired the university's special budget for this project in 2018.
As of November 15, 2026, the Digital Archive provides 2,241,293 images of 27,190 titles.
