A cost comparison study was made of Excerpta Medica's abstracting journals, based upon actual costs to a library. Unit costs were determined for six sections of EM as compared with six corresponding abstract journals. On average, EM sections were found to be 138% more costly than corresponding abstract journals. The effects of splitting of EM journal titles were also analyzed. This practice increases the price of a total subscription to EM and makes comprehensive information retrieval more difficult. A survey of medical school librarians as users of EM points to dissatisfaction with its increasing price, particularly when it results from title splitting.
基于图书馆的实际成本，对《医学文摘》的摘要期刊进行了成本比较研究。确定了《医学文摘》六个部分的单位成本，并与六种相应的摘要期刊进行了比较。结果发现，《医学文摘》各部分的成本平均比相应的摘要期刊高138%。还分析了《医学文摘》期刊标题拆分的影响。这种做法提高了订阅《医学文摘》的总成本，并使全面的信息检索更加困难。一项针对作为《医学文摘》用户的医学院图书馆员的调查表明，他们对其价格上涨感到不满，特别是当价格上涨是由标题拆分导致的时候。
