摘要：The season of 1929-30 for the Exchange opened with the October broadcast, October 7th. Lists were issued regularly thereafter each month, with an extra list in March and a double list May 15th, making eleven lists in all, or fifty-four lots of material, offered by fortytwo different libraries from their duplicates. Some gave in large measure from their accumulation, and others as they were able. Some gave because they were moving into new buildings, but all gave cheerfully and with the thought that they were benefiting others and paying in part their debt to the Exchange for past favors. Fifty more mimeographed pages were listed than last season, or a total of 192 pages. Thus many thousands of items were presented for the membership to check from and good use was made of the opportunity and much valuable material changed hands. Mention should be made of the short lists of wants that were broadcast, as this service was increased over last year, and great credit should be given those libraries who responded to these requests.
