The total number of substantive articles published in a random group of U. S. biomedical journals increased 34 percent from 1957 through 1962 and 52 percent from 1952 through 1962. Likewise, the total number of subscriptions increased 28 percent from 1957 through 1962 and 47 percent from 1952 through 1962. On the other hand, the rise in the number of preprints and reprints distributed reached its peak from 1952 to 1957 (37 percent); by 1962 the rate had declined, with an increase of only 4 percent from 1957 to 1962 and thus of only 43 percent for the entire period, 1952 through 1962. Replies from publishers indicate that at present the provision of preprints and reprints is merely a service in the case of almost 90 percent of the journal titles and not an enterprise undertaken for significant profit. The cause of the decline in offprint distribution should be investigated.
在一组随机选取的美国生物医学期刊中，1957年至1962年期间发表的实质性文章总数增长了34%，1952年至1962年期间增长了52%。同样，订阅总数在1957年至1962年期间增长了28%，1952年至1962年期间增长了47%。另一方面，预印本和重印本的分发数量增长在1952年至1957年达到峰值（37%）；到1962年，增长率有所下降，1957年至1962年仅增长了4%，因此在1952年至1962年整个期间仅增长了43%。出版商的回复表明，目前几乎90%的期刊提供预印本和重印本仅仅是一项服务，而非以获取可观利润为目的的业务。应调查抽印本分发量下降的原因。
