For recording credits a form, similar to the one shown in Fig. 15, should be used. This may be on a card or in loose leaf. A card is used for each ad, in each publication—that is, if there are seven insertions in the Technical World in one year, seven record cards will be used—one for each insertion. These cards or sheets are to be filed under the names of the publications.

On the back of the card the form shown in Fig. 16, is printed. This provides for a daily record of sales resulting from the inquiries recorded on the face, or from the ad if it calls for direct orders. These forms supply all necessary data for a complete statistical record for each publication. Too much time would be required to look through all of these cards every time information is desired about a given publication; a more condensed record of total results should be provided.

All of the information of practical value can be combined with a record of insertions on the form shown in Fig. 17, using a sheet for each publication. The record includes the date of order, space, subject, copy No., cut No., dates of insertion, checking, and proofreading, the date and amount of bill, and the number, amount, and average cost of sales. The record of sales should be entered monthly from the detail record.

These sheets are filed in a loose-leaf binder, indexed alphabetically under the names of the publications. One sheet will accommodate the full yearly schedule for a monthly or weekly publication.
