A Danish Charging System. libraries, in which an indicator is not in use, it is of great importance to have an easy method of finding the book which a borrower has, or the borrower who has a distinct book. The following method is in use in the public library in Helsingfors, Finland, from which the annual loans are more than 60,000. It has been devised by V. Vasenius, in his pamphlet Rad romnde folkbiUiothek I. : Varden af folkUUiothek. I have varied the method a little for the use of Horsens Public Library, where the loans are fewer. Perhaps this method may also be of interest to English librarians. The method used in Helsingfors is as follows : Every borrower has a ticket, on which is written the borrower's number. Before the borrower receives a book, the number of the book and of the borrower are written on a little card (a square inch or more in size), the first number on the left, the other on the right side, and then the borrower may go, after having left his ticket.

From day to day the cards are inserted among the cards already received in the numerical order of the books. The cards are kept in a little paper, or tin, box. Between every hundred cards a card a little higher is placed, and on this card (or guide) the number of the hundred (100, 200, &c.) is written. The borrowers' tickets are arranged in the same way. When the book is re- turned, the corresponding card is taken out and placed in another box. On the card the number of the borrower's ticket is seen, and it is removed and returned to the borrower, who again can have another book. When the loan time is over the cards taken out are arranged according to the date, and the cards on which
