Quantitative tools for collection management: a proposal for Library Systems of the Province of Milan

Reflections on bibliographic evaluation criteria and the need - current in every library structure - to well define the collection development policy are topics now consolidated in the Italian professional forum, even with a delay if compared to the Anglo-Saxon world.

It is recent, on the contrary, the attempt - relevant, in my opinion, on the national scene - to conjugate these subjects to a more general managerial and organizational approach applied to the "system library" on the whole [1]. In this sense, the concepts of collection management, collection development planning, collection evaluation and review, cooperation and acquisition choices coordination are extremely important. I believe that this method allows making concrete and practical these arguments.

Moving from that argument, the aim of this paper is to present the activity of the work group composed by representatives of some library systems of the Province of Milan [2] and to show the methodological path developed.

This path - shortly described in the next paragraphs - aims at sharing a methodology for collection development and management in cooperating public library networks, which have different levels of inner resource integration.

To refer more percisely to our reality, I will give a summary of the organization of the provincial library [3].

Before deepening the question, I think it is helpful to propose again two preliminary personal considerations [4] that somehow influence the whole approach of this paper and that can be so summarized:

• a library system, by its nature, cannot be confined to offering services to joined libraries (aiming correctly at lower costs or a high quality of services), but must have the goal - more complex - of realizing a coordination in management policies of joining libraries; in these policies, collection management policies must be priority.
• in a library system, in which components (the libraries) are deeply integrated and interconnected by existing union catalogues and by a heavy use of interlibrary loan, it is very important to develop cooperative collection development policies so to set up correct relations between the library and the network; in this sense, for instance, defining minimal acquisition standards or realizing analysis of user needs are essential procedures to avoid unbalances and parasitical attitudes in cooperating libraries.

1. The aims of the group and the structure of the methodological model

Interests of the group in building qualitative and quantitative tools for collection management has resulted in the definition of the following goals:

• Promote the development of a fully aware collection management process in public libraries of the Province of Milan
• Propose to librarians a work method adaptable to the varied territorial context, where differences in dimensions of the communities exist:
• Apply the potential of interlibrary cooperation to collection development;
• Propose work instruments precise and easy to use and not too complex;
• Create the basis for writing policy statements for collection management.

 In summary, we wanted to propose an organic (?) approach to collection management, which would help librarians to share a work method that defined and set a collection development path, and avoided personal choices and choices based on not unbiased data or in contrast with the mission of the public library.

The plan of operation - addressed to public libraries in suburban library systems of the Province of Milan - is mainly based on five methodological steps that I will shortly describe [5]:

We propose to identify and set what "the institutional scopes" of public library collections are, that is those subject areas that various guidelines and documents (IFLA Guidelines, Unesco Manifesto, national and regional laws) consider as compulsory in library collections. Outside those scopes, we believe that materials circulation rate must be the most important evaluation factor for cohesion and relevance of collections for users. We must precise that we refer to public libraries, not to preservation libraries.

Tab. 1 - Institutional scopes of the collections

b) Definition of the community profile to which the library refers

Analysis of the main demographic and sociological factors of the community to serve (divided in 5 areas of analysis) represents an unbiased reference point towards which we must set the library service and consequently the collection profile.

Tab. 2 - Community analysis: the 5 macro-areas of analysis

• division of libraries in categories according to their size; they are called families [see table 3]
• definition of standards goals for all main criteria of evaluation of collections;
• division of collections according to an homogeneous subject distribution, which uses modified divisions of Dewey [see table 4];
• definition of an evaluation system which produce - by using the database management system of the library - periodical reports on collection management and use rates of collections.

Tab. 3 - Families categorization and definition of standard goals

Tab. 4 - Homogeneous distribution of collections in 27 subject areas

d) Identification of subject areas over/under-sized and levels of intensity of collections

Analysis of circulation rates and estimation of balanced index of collections increasing, as divided according to the homogeneous distribution of collections, will allow to define which subject areas are oversized or undersized on a systemic scale (in table 5 we present the analysis made on the children collections (age 0-14) of Vimercatese Library System). Application of the Conspectus model, adequately adapted, will allow defining for every subject area and for every library, what must the planned level of collection intensity be (minimal information level, basic information level, study or instructional support level).
