When using the British Library (BL) integration in Talis Aspire Digitised Content (TADC), there are a series of steps taken before the order is completed. Matching your metadata in the request to the correct item held by the British Library is a key step in the process.
Matching - how does it work?
Automatch in the BL on demand service uses an API to pass metadata from the TADC request (ie. author, title, ISSN) through to the BL remote supply catalogue. This then attempts to match each element of the request with records in this catalogue. Each element match is given a score, with the results then ranked as 'High Match', 'Possible Match' or 'No Match'.
Note: Elements that don't match do not result in a negative score and will not reject an result from the BL matches.
Matching - what other checks are done?
As the matching system is not 100% accurate, it requires a human operator at the BL to act as quality controller and decide whether to submit the high match as an order or not. The outcome of this is that not all orders sent from TADC will be fulfilled if the High Match is not correct at this point.
What the BL says about the quality of the data we send
"Your match requests are perfect in that you have cited all the bibliographic information available. I don’t think you can improve on what you already have."
Improvement - Feb 2018
As matching is not exact if the identifier (ISBN/ISSN) is not found as explained above, with some reports of High Matches returning unrelated items. We have made an improvement by adding an intermediate screen for you to confirm the right resource has been matched before placing an order.
