Beginning in 1964, the orders are separated from the general Correspondence (Series 1). They include orders for both taping services and for Pioneers in Brass and, after October of 1969, Cornet Talks by Herbert L. Clarke, a booklet of 21 pages edited by Bridges. The orders consist of two types, prepaid and billed. In the case of those that arrived with checks or cash, they are filed by the date of the order. In the case of those billed (usually orders by university or public libraries), they are filed by the date of payment. The date of payment was noted by Bridges on the envelope of the payment. In those cases where he wrote only "Paid" on the envelope, the date of the postmark is used. This date is indicated within brackets and the envelope discarded unless there was other information noted on it. In some cases the Bridges' invoice is not associated with the payment and in those cases the invoice is filed by its date and the payment by the date noted in brackets as indicated by Bridges on the envelopes, which were discarded unless there was other information noted on it. Note that in those cases when an order also included personal comments, it is filed in the "Correspondence" series, as is any material relating to the sale of records from Bridges' collection. Also note that beginning with January of 1982, after the death of Glenn Bridges, the correspondence and the orders are filed together in the Correspondence Series.
