But the important thing to stress is that a collection is not a folder, but a tag. A lot of people misunderstand this, and it's a very important distinction. It's the fact that it is a tag which allows the same book to appear in multiple collections, while at the same time only having a single copy of it on the device.

Thanks, Harry, for explaining this again in an easy-to-understand way
For the technically inclined: Think of the book <-> collection relation as an n:m relation in a database. And - guess what - that's exactly what it (logically) is in the underlying SQLite database. Except that the people who implemented it might want to revisit their cs1xx course material (Introduction to Databases), because they must have been in a coma during the
normalization part of the lecture. The database actually does it in the worst possible way for an n:m relation, namely using NF˛ at both ends of the relation.
