But after a time certain economies were introduced, columns 2, 7, and

9 being omitted, and day-books in this later form, perhaps with the

arrangement slightly altered, are in common use now. Of course it is

plain that a book on issue was entered in the first vacant line of the

day-book, and the progressive number, borrower’s number, and date were

carried on to its label. On return, the particulars on the label pointed

out the day and issue number, and the book was duly marked off. It will

at once be seen that this form of ledger only shows what books are out,

but cannot readily show the whereabouts of any particular volume without

some trouble. As to what book any reader has is another question which

cannot be answered without much waste of time. A third disadvantage is

that as borrowers retain their tickets there is very little to prevent

unscrupulous persons from having more books out at one time than they

should. A fourth weakness of this ledger is that time is consumed in

marking off, and books are not available for re-issue until they are

marked off. For various reasons some librarians prefer a system of

charging direct to each borrower instead of journalising the day’s

operations as above described. These records were at one time kept in

ledgers, each borrower being apportioned a page or so, headed with full

particulars of his name, address, guarantor, date of the expiry of his

borrowing right, &c. These ledgers were ruled to show date of issue,

number of book, and date of return, and an index had to be consulted at

every entry. Now-a-days this style of ledger is kept on cards arranged

alphabetically or numerically, and is much easier to work. Subscription

and commercial circulating libraries use the system extensively. The main

difficulty with this system was to find out who had a particular book;

and “overdues” were hard to discover, and much time was consumed in the

process. To some extent both these defects could be remedied by keeping

the borrowers’ cards and arranging them in dated trays, so that as books

were returned and the cards gradually weeded out from the different days

of issue, a deposit of overdue borrowers’ cards pointing to their books

would result. Another form of ledger is just the reverse of the last, the

reader being charged to the book instead of the book to the reader. This
