Talis Aspire Digitised Content - Request identification and edition checking

Introduction

Since November 2017, Talis Aspire Digitised Content (TADC) uses two streams of data to identify editions xISBN (from OCLC) and Nielsen Book Data to identify resources for the purposes of determining the work and all of its manifestations. When TADC is unable to identify a resource, it currently stops the checking process, and puts the request into a manual copyright checking process.

Resource identification sources

We have demarcated the Nielsen Book Data and xISBN request identification step from the rest of the copyright checks by introducing a number of alternative sources from which we will attempt to identify a request. TADC will still try to first identify a resource in xISBN, but it will no longer 'stop' if it's not found.

We will search each data source and if unsuccessful, will move on to the next source in the sequence detailed below. If we are unable to identify the resource using any of the below sources, it will be referred as “Unable to identify the resource” and will require a manual copyright check. 

  1. Nielsen Book Data and xISBN
  2. University’s library catalogue
  3. multiMarc (is a union catalogue set up to collect the needed bibliographic data from a series of major libraries, with open catalogues, around the world)*

If a request is identified in the catalogue or multiMarc, TADC takes the ISBNs found in the catalogue lookups (e.g. multiple 020s, etc.) and uses them to query our internal bibliographic store. If a match is found, the concierge then tries to match xISBN with the ISBNs from the library catalogue and our own bib store. It then looks for existing works in TADC with all of the ISBNs that have been found for the work. If the ISBN does not match, TADC explicitly tell the user that it could identify the resource, but not the work.

Once the request is identified, in the UK, TADC will then go on to check the CLA Check Permissions API.

Edition checking

Whilst using the latest edition is no longer a requirement of the licences of any of our supported regions, it is still a valuable check for a lot of our customers who chose to enable this by using the request outcome options in the settings area of TADC.

If you have the latest edition request outcome option in the settings area set to refer or reject when it is not the latest edition, TADC will inform you that it is unable to determine the latest edition and this requires a manual check. This will be clearly outlined in the worklog, as well as a clear notification at the top of the request.

Copy limit checking

Copy limit checking for all of our supported regions is performed at the work level. In order to do this, TADC identifies all manifestations of a work and checks that the copy limit has not been exceeded for the work on a course or for the institution (depending on the copyright region).

If the work is cannot be identified as the latest edition in the combined data source of Nielsen Book Data and xISBN, TADC will refer for manual clearance when it is unable to perform a copy limit check and indicate why in the worklog.

When the data source for identifying the request is multiMarc or the university’s library catalogue, TADC cannot determine all of the manifestations of a work, so, therefore, it cannot determine the copied amount for the work and can’t perform a copy limit check. It can, however, determine the copied amount for that specific edition. TADC will refer for manual clearance when it is unable to perform a copy limit check and indicate why in the worklog as well as the notification at the top of the page described above (except for our Australian customers where copy limit applies across the institution and not the course)
