There is a problem that the number of registered papers in the Tsukuba Repository is decreasing in the index list.

It is possible to view them by following the links in CiNii etc., or by using the handle net ID (e.g. http://hdl.handle.net/2241/XXXXXXXXXX) or DOI assigned to each article, but they may not appear in the search results even if you search in the Tsukuba Repository.

We are in the process of reporting this problem to the system provider and requesting an immediate improvement.

Due to this problem, we are suspending new registrations at this time. The resumption date has not yet been determined.

We apologize for any inconvenience this may cause and ask for your understanding and cooperation.
