摘要:In your letter of April 2, 1958, addressed to our offices in Amsterdam, you inquired as to the possibility of our publishing a cumulative index for the Excerpta Medica journals. I have recently returned from Amsterdam where we had a very full discussion of this subject at the annual meeting of our Chief Editorial Board. We have given very considerable thought over the past year to the publication of a decennial index covering the period 1947 through 1956 but have regretfully come to the conclusion that without some outside financial aid the Foundation could not bear the enormous costs involved. Moreover, we seriously doubt whether it would be possible to establish a price which would be within the reach of the average medical library, operating on an already limited budget.
