I am fiddling about with Calibre and my Sony PRS-T2 reader and I am trying to figure out how to manage the collections in my reader.
What I did in Calibre is add multiple tags to my books like, for instance, Science Fiction as the main tag plus additions like Space Opera, or Adventure or...
The result gets to be Science Fiction, Space Opera, for instance.
I discovered that only the first tag appears in my Reader and thus forms a collection.
If that book belongs in a series that book appears in my reader twice: one as a part of the books with a tag and secondly because it is part of a series.
I have several questions about this:
1: is it possible to have collections generated on the basis of more than 1 tag?
2: is it possible to have a book with tags as well as being a part in a series appear only once in my reader?
I have seen postings in 2009 and 2010 about this subject but those did not quite cover my problem as far I could make out.
Anyway, help would be very much appreciated.
