It is only the image capture stage of the digitisation chain that is being contracted out to an external bureau. There is no way of out-sourcing responsibility for the entire digitisation chain. The involvement of an external bureau requires a clear understanding of the end-product and attention to detail when any Service Level Agreement is put together. Advantages Disadvantages Quick delivery time. Copyright of digital images needs to be assigned to client in the contract, and not retained by the bureau.
Costs can be favourable compared to in-house costs.
Lack of control over scanning environment. Range of scanning equipment available. Need to transport materials. Bureau absorbs equipment depreciation and obsolescence costs. Digital images need to be 'fit for purpose' and cost effective.
