One common request at a library’s information desk is for a sequel of a book title or where to begin reading a roman-fleuve such as "Harry Potter". Experienced librarians might know the answers to the most famous titles, but there is not much evidence that they can retrieve such information from the library’s catalogue. This study investigates inter-work relationships in seven Online Public Access Catalogues (OPACs) and looks at the phenomenon with an empirical, exploratory approach. Based on previous empirical studies about cataloguing praxis, this study seeks to add up to those efforts by analysing catalogue records to determine the effects of past and current standards in cataloguing sequences of novels. Some records have such information coded in several fields. As a maximum, it appears six times, although it is uncommon to occur more than three times. On the other hand, as should be expected, the Machine-readable cataloguing (MARC) fields for the information about the position of a novel within the roman-fleuve match the cases where the title of the roman-fleuve is given. Cataloguing practices have evolved from paper format, which posed challenges in physical space, into machine-readable and relational databases. OPACs are still debuting in a new era with linked data. Swedish OPACs still do not deliver much information regarding roman-fleuve and its parts. The data shows, however, that a fair amount of records offer the possibility for conveying such information to the users if the OPACs look in the proper fields of the catalogue record.
