Drawbacks
There are certain drawbacks and disadvantages also in centralization of processing.
1) Some libraries may not be able to afford the operational costs involved. Or the effectiveness of the cost involved may be marginal so that it may not make much difference between centralized and individuul/se!fpnouexxiu8 for some libraries. 79 Centralised Cataloguing, Cataloguing-in-Publication and Pre-Natal Cataloguing
2) The libraries which are clients to the centralized processing may have practices different from the central organisation. For example, the scheme of classification or the catalogue code followed by the library may be different from those followed by central organization. Even if they are same the library may be following different editions. These local variations are deterrents in opting for centralized processing.
3) For purposes of individualizing a document through its Call Number and for purposes of deciding the number and type of entries required for the library the participating library still has to keep skeletal staff in the processing sections. That is to say a participating library cannot completely dispense with staff in its processing sections.
