Use of Scientific Periodicals
D.J.URQUHART
In the United Kingdom it has been decided to plan a National Lending Library for Science and Technology, and it is intended that this library should take over from the Science Museum Library the general responsibility for providing a lending service to organizations in the United Kingdom. To obtain some data for this planning operation it was decided to analyse the issue records of serial publications of the Science Museum Library, which at present has the largest collection of scientific literature in the United Kingdom. The Science Museum Library is actually within the buildings of the Imperial College of Science and Technology (South Kensington, London, S.W.7), and functions, in practice, as the main library of that college. The library has a reading room which is open to the public, and it lends to the staff of the Science Museum and the Imperial College, and to over 1200 outside organizations. These include universities and colleges, industrial organizations, research organizations, and government departments.
At present the library is receiving about 10,000 current serials. In all, it contains some 430,000 volumes. The subjects covered include all the sub-divisions of the pure and applied sciences, with some restrictions in the clinical medicine field. About 80% of the total volume of receipts and issues are serial publications.
The records examined were the counterfoils of issue forms for literature returned to the shelves from the reading room or from borrowers during 1956. An unknown number of these forms may have been lost, but the missing forms would probably amount only to a few per cent., and they are likely to have been a random selection of the total.
The primary object of the analysis was to provide data for planning purposes. It was hoped, for instance, that the data would answer such questions as (a) which serials are so heavily used that they must be held by the National Lending Library, (b) what back runs of serials should be collected, (c) which serials should be duplicated or bound in parts, (d) which serials are so little used that one copy either in the future Science Museum Library or the National

Lending Library should be sufficient. However, as this survey of actual use of scientific serials is probably the largest which has ever been made, it was thought that a general account of the results would be of interest.
The analysis was made by punching a Hollerith card for each item issued from the shelves. This gave (a) the shelf mark of the serial (this is unaffected by a change of title); this was added to the counterfoils where necessary; (b) the type of user: A, borrower in the Science Museum or Imperial College (i.e., “internal loans”), B, other borrowers (i.e., “external loans”), C, reader in the Science Museum Library’s reading room; (c) the date of publication of the item used where given. In all, 87,255 cards were punched, and they were divided up as follows:
A
Loans to Science Museum and Imperial College
2,255
B
Loans to other borrowers
53,216
C
Issues in the reading room
27,161
4623 (5.3%) of the forms were rejected, mainly because they did not give the publication date of the item issued. The remainder were sorted by date, and this gave the results shown in Table I.

a Owing to the methods by which the forms were selected two copies of the same reading room issue form may have been punched on some occasions. This has not happened in more than 10% of cases, and will not have affected the total number of periodicals used.
In interpreting these results the following should be noted:
The Science Museum Library lends in the main to organizations which have some library resources of their own.
The current volumes of some 500 periodicals are available on open access in the reading room.
The Science Museum Library does not lend reference publications such as abstract publications, and during 1956 the 1940 onwards volumes of 72 periodicals were on a non-loanable list. This list is given in Appendix A.
Binding operations during 1956 will have reduced the availability of material published during 1954.

Whilst there is no Imperial College Library several of the departments of the college have their own libraries.
The analysis by serial shelf marks showed that, in all, 7064 serials were used.
The following details of the number of serials used are available:
Number of serials borrowed by the local staffs
1,063
Number of serials borrowed by others
5,632
Number of serials used in the reading room
3,518
Total number of serials used by all types of users where publication date was 1950 or afterwards
4,753
Total number of serials used by all types of users where publication date was 1949 or earlier

From the general point of view the most interesting figures relate to the loan issues to external organizations. Tables II to V illustrate the results obtained and make it possible to compare the number of issues from the Science Museum Library with the total number of holdings as given by the British Union Catalogue of Periodicals (BUCOP) for the main libraries in the United Kingdom.

External organizations will naturally only borrow from the Science Museum Library scientific literature which they do not hold themselves, or which they cannot obtain from some more accessible collection. Thus the external loan demand on the library is, in general, only a residual demand, although many bodies may make a habit of always applying to this library first. Nevertheless, possibly because so many external organizations (some 1200) use the Science Museum Library, it appears from the examples in Tables II to V, and from Table VI, that the use of the copies of a serial in the library is a rough indication of its total use value in the United Kingdom. An analysis of the type of libraries which hold little used serials indicates that, in general, they are the general and not the special libraries. So that it is probable that, as a rule, the copy of the serial publication in the Science Museum Library is more used than a copy of the same serial elsewhere. However this may be, it is very-clear that it is not the abundance of sets of certain serials in other libraries which results in the Science Museum Library’s holdings of these serials being so little used.

An analysis of the serial titles used showed that 2769 of them were not current according to the Hand List of Short Titles of Current Periodicals in the Science Library, Eighth Edition, 1956. This list contains references to 9120 serial publications, and 4821 of these were not used at all during 1956. The greater proportion of users would have been using, during 1956, the 1953 edition of the Hand List, which contains a smaller number of titles.
These figures do not necessarily mean that the Science Museum Library is collecting some 4821 serials which will never be used, but they do indicate that the demand for a large number of titles is very small. For instance, if the library contains 7500 serials, each of which is used on an average once every two years, we should expect to find in a particular year that of these, assuming random distribution of demand

Appendix B gives a list of the titles which were borrowed 10 or more times for any of the publication decades 1900–1949, and indicates the decades concerned.
This list should be of value to special libraries in the United Kingdom in indicating what serial literature published in the period 1900–1949 they should consider obtaining or retaining.
The average period of loan of a serial publication lent by the Science Museum Library is about 23 calendar days. Hence, a volume which is lent on an average once per year should be available on demand for 94% of the time.
Considerations such as these make it possible to determine what must be done regarding binding periodicals in parts, or duplicating copies to achieve any particular standard of service (e.g., a minimum of 90% available on demand for any title). The survey of the actual use data indicates that, as a rule, binding parts of periodicals separately in a light binding would be cheaper in providing an improved standard of service for frequently used serials than duplicating or triplicating. These considerations are, of course, based on the assumption that for any title and time since publication the demand for it is random, but has a given average value. This assumption has not been tested. Theoretically it would be possible to test the assumption by comparing the theoretical number of times material is on loan when required with the number found in practice, but this would involve more data regarding the state of the bindings and of the volumes per year than is immediately available on the punched cards used.
Conclusion
The primary purpose of this paper was to record the facts as far as they are available, and to leave to others the application of the data to the problems which face the users of science literature throughout the world.

The analysis, however, confirms one general idea. Extensive use of scientific literature is confined to a small fraction of the total output. Even in a library which is designed to deal with the residual demand from libraries, about 1250 serials (or less than 10% of those available if the non-current serials are included) are sufficient to meet 80% of the demand for serial literature.
Indeed, the figures suggest that perhaps three-quarters of the current serials in the Science Museum Library are so little used that one loan copy of these serials somewhere in the United Kingdom should be sufficient to meet the needs of all users in the United Kingdom.
This analysis focuses attention on the old questions: (1) Is the small use of a large number of serials due to the low value of, or to ignorance about, their contents? (2) If it is ignorance, what can be done to eliminate it? (3) If the contents are designed only for a very small audience, should the papers continue to be published in the traditional way?
