What do I do when I want to extend the borrowing period of a loaned out book?
From OPAC, you can check and renew the materials you have borrowed from the university library.
1. First, log in to OPAC.
2. "User Inquiry" appears after login. Click "Borrowing" there.
3. "Borrowing list" appears. Place a check mark beside each material you want to renew, and click [Renew].
In "Borrowing list," you can check the borrowing status: where (borrowing library), what (bibliography information), and when (Due Date).
4. Click [OK] in the pop-up.
5. The update is completed when the return date is extended.
If the update cannot be completed, the screen displays this fact and the reason for it.
From "Borrowing list", you can check the number of renewals by clicking "Bibliography information" for loaned out materials.
Note the following points concerning renewal.
- Renewed return dates are calculated based on the special online rules of each holding library.
- An online renewal is updated on the day that the update process is executed. Note that the borrowing period is not an added period from the due date.
- Renewal is not possible in the following cases:
- Materials already reserved by another user
- Overdue materials and materials in a restricted borrowing period
- Where update may not be possible depending on the material type (textbooks, serials, etc.)
How do I cancel a reservation?
1. Log in to OPAC.

2. Click "Reservation" from User Inquiry on the OPAC top page.

3. The reservation list screen appears. Place a check mark beside the material whose reservation you want to cancel, and click [Cancel Reservation].

4. Click [OK] in the pop-up.

5. "Canceled" appears under Status upon the completion of the reservation cancellation.

What happens when materials become overdue or have borrowing restrictions?
Be sure to return all materials within their borrowing period.
[Notice]
- Cancellation of a borrowing restriction takes effect on OPAC at about 6:00 a.m. on the cancellation date.
If you are a user whose borrowing is restricted but you want to renew or reserve different materials currently checked out from the same library/room, do so after 6:00 a.m. on the borrowing restriction cancellation date. - Libraries/rooms have book drops. Any materials returned after hours to the book drop of a library are basically considered returned on the previous business day with the return processed on the next business day.
- Even if your account still had overdue materials and a borrowing restriction, you could apply from OPAC to copy a book (get a copy from another library) and borrow a book (back-order the actual book). You could also make a library purchase request (* Being prepared).
What are the tags displayed on the tag search screen?
When grouping multiple materials, the name that is given is the tag.
Search by "_____ seminar reference book" or Library event Name, anyone can bring up the same list of materials.
For example, try clicking a tag in "New tags," "Recent tags," or "Popular tags." Then, materials that have these tags are displayed.
What should I do if I want to search tags?
You can search the title or full text of tags in any of the following five ways.
- See "
New Tags" on the top page.
- Select "Search Tags" under the search bar on the [Bib Search] tab.
- In [Basic Search] on the [Bib Search] tab, enter a check mark for "Contains tag."
- In [Advanced Search] on the [Bib Search] tab, select "Tag" from the pull-down menu and search the materials.
(In contrast to the basic search, you can perform a search with multiple conditions.) - Select "Search Tags" from the catalog search menu.
How do I return to the original search result list after a refined search from the left menu on the search result list display screen?
The following is the example narrowing Holding Libraries "Central library".
Cancel the search conditions for this holding library. Then, to return to the original search result list, click the red x button in the blank area under "Selecting conditions."
Even if you have performed multiple refined searches, you can cancel any narrow-down search condition by using the above method, regardless of the order of the searches.
Suppose that you perform a refined search of a holding library, select a bibliography on the bibliography search result list screen, and then move to the bibliography details screen. Even after that, you can still cancel the refined search of the holding library and perform a refined search of another library.
