MODERATELY AND HEAVILY USED BIOMEDICAL JOURNALS
Bulletin of the Medical Library Association
|January 1, 1964
Summary
A study of medical journal usage at Columbia and Yale found that a core of 262 journals met 80% of demand. This research identifies essential current journals for medical libraries.
Area of Science:
- Library and Information Science
- Medical Librarianship
- Bibliometrics
Background:
- Medical libraries face challenges in curating comprehensive journal collections.
- Assessing journal usage is crucial for efficient resource allocation and collection development.
Purpose of the Study:
- To identify a core list of frequently used medical journals.
- To determine which journals satisfy a significant portion of user demand at major medical libraries.
Main Methods:
- Analysis of canceled charge slips for journal issues from 1959 to mid-1962.
- Examination of circulation data from Columbia and Yale Medical Libraries.
Main Results:
- A core of 262 journal titles provided 80% of the recorded usage.
- Sixty-seven journals accounted for over 50% of the demand.
- Columbia and Yale Medical Libraries received nearly 2,000 and over 1,500 journals, respectively.
Conclusions:
- A small percentage of journal titles fulfill the majority of user needs.
- The findings can inform collection development and resource sharing strategies in medical libraries.

Overview
01:40Hormonal Regulation
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
01:33Hormonal Regulation
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.
02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
01:13Bioequivalence studies: Biowaivers
In certain scenarios, in vitro dissolution tests can replace in vivo bioequivalence studies. This is particularly true when a drug product, though available in varying strengths, maintains proportional similarity in its active and inactive ingredients. In such cases, the need for in vivo bioequivalence studies for lower strength variants may be waived, provided dissolution tests and in vivo studies on the highest strength yield satisfactory results.Bioequivalence can be indicated through...
