Consequently, records of different levels of completeness and standard compliance will coexist within the catalogue. It is a common situation, but it will be particularly intricate because it won’t be a simple case of printed and electronic books having different quality records. Some ebooks will have richer records because of the data retrieved from a preexisting printed book record, and the reverse might be true too. Thus, the very process will induce such a symbiosis between records that we won’t be able (should we want it) to separate workflows for printed and electronic books.
