A basis of the invention is that an existing database (14) of a library contains data of all the books arranged alphabetically by class and the data of the books on loan. This data is transferred to a terminal equipment (11). A bar code (17) identifying the book is attached on the back of each book, and the data of the books on shelves are read in succession by a bar code reader (15) connected to the terminal equipment. As a bar code is read, an application program in the equipment compares the data of a book with the data of the database of the library program and calculates, on the basis of bar codes and the data of the database, if a book is in the proper position thereof in relation to other books and if an absent book is missing.</p> |
