I have been reading messages on this topic with interest, because I too straddle both professions. Until recently I worked at the Science Museum, London, where as well as being in charge of the Library I was centrally involved in developing systems to record and retrieve information about museum objects. I think that it is futile to try to draw rigid distinctions, because the work that is done in museums, libraries and information services forms a continuum and any person or institution can be positioned at any point on that. A few pointers which seem to me to distinguish different parts of the landscape, however, are as follows: 1. Librarians are primarily concerned with information in textual form; museum people are primarily concerned with physical objects. 2. For a librarian, the information content is the core element. A photocopy, transcription, reprint, microfilm or electronic version is generally equally as good as an original. For a museum, authenticity of the physical object is crucial; museums have models and replicas, certainly, but if they have no original objects they are not really museums. (They may be "science centres" or the arts equivalent - another part of the continuum). 3. Libraries which have collections of rare and unique publications, or archives, have some museum aspects in their functions. 4. Collection of non-textual information, such as pictures or sounds, can fall near to museums or to libraries, depending on whether the collection is seen as "art originals" or "images". Is the important thing the physical item or the "message" it contains? 5. Both museums and libraries have some techniques in common, particularly in identifying and describing items, and recording them in a consistent way so that they can be retrieved reliably when needed by a user. These techniques were developed first in libraries and museums are now applying them. There is some re-inventing of wheels, some building on what has been done, and some leap-frogging (e.g. museums can learn from the problems of libraries lumbered with poorly-structured subject heading schemes and build good thesauri for themselves instead). 6. Libraries have traditionally given a higher profile to enquiry services, seeing it as their responsibility to help users to find information; whether it comes from their own library or elsewhere is not important - the library is seen as a gateway to the national and international information network. Museums have traditionally dealt with enquiries in a less structured way; individual curators deal with by them as they choose - sometimes very detailed replies and personal research, sometimes nothing. Few museums make the enquiry desk their focal point and staff it permanently with professionals. 7. Museums have traditionally taken the initiative in presenting their material to the public and telling a story; librarians have done this in publications and displays, but they have given priority to the agenda set by the enquirers who take the initiative of approaching them. 9. Libraries always have publicly-accessible catalogues of their collections, and are expected to produce any item for consultation on demand; few museums can do this. All this is history, though. We should not be looking for differences which divide but for similarities which unite. As long as we have a clear mission statement, we should use all the techniques we can find to achieve it, and so long as we are able to apply them competently we need not worry too much about professional labels.
