Data making of CiNii Books
The data which becomes the origin of CiNii Books is come from NACSIS-CAT/ILL (union catalog). Via NACSIS-CAT/ILL, university libraries and some other libraries are creating data through cooperative data entry (shared cataloging).
Member libraries of the NACSIS-CAT/ILL are registering data of holding books and journals into the database daily.
We update the data of CiNii Books at the time of closing time on Saturday in predawn on following Monday.
