The increasing demand for more intelligible records—for facts—has stimulated the ingenuity of accountants in devising forms that will not only accommodate the records desired but will permit of their being made with the least labor. Special forms exactly suited to the records which they are to contain, are now made for every purpose. Labor-saving devices and methods have minimized the drudgery of bookkeeping. The bookkeeper who would rise above mediocrity requires something besides the ability to record business transactions in the proper columns of books prepared for him. He must know how to devise forms and books, how to adapt correct principles to the building of a system of bookkeeping for any line of business. If certain facts assume importance, he must know how those facts can best be obtained and recorded. To assist in familiarizing the student with the more modern methods, this section is devoted to illustrations and descriptions of special forms of books for various purposes. The student should devote careful study to these forms, for while they have been in the main devised to meet special conditions, the principles can be adapted to any line of business where similar conditions exist. SPECIAL LEDGERS =22. Loose Leaf Ledgers.= A loose leaf ledger is one in which the leaves are removable. Instead of the sheets being bound in solid book form, each leaf is a separate sheet ruled for one ledger account. The sheets are filed or bound in what is known as the binder, being securely held in place by a mechanical device. The binder can be locked so that only the person holding the key can insert or remove the sheets. The loose leaf ledger is indexed either numerically or alphabetically. When the numerical method is used the sheets are numbered and placed in the binder in numerical order which gives the same arrangement as a bound book. A separate index is required with the numerical method. The alphabetical method of indexing necessitates the use of sheets on the edges of which are tabs or projections printed with the letters of the alphabet. These index sheets are placed in the binder in alphabetical order and the ledger sheets are placed between them. The alphabetical method is preferred by many as it makes the ledger self-indexing. Another method of indexing is a combination of the alphabetical and numerical. The alphabetical index sheet is used, and under it are filed all accounts of persons whose names begin with that letter. These sheets are numbered Account No. 1, No. 2, etc., and the names are written on the index sheet, followed by the account number. This practically divides the ledger into separate numerical ledgers for each letter of the alphabet. [Illustration: Fig. 20. Loose Leaf Ledger ]
