The trick is not to think of it as meta information. It makes sense that you've got meta information about the library which you want to store, like the address where this book library is located. set attribute of all models in backbone collection Ask Question Asked 10 years, 5 months ago Modified 6 years ago Viewed 20k times 18 I understand that using pluck method we can get an array of attributes of each model inside a backbone collection var idsInCollection uck ('id') // outputs 'id1','id2'. Let's say you are thinking of a Library (collection) of Book (model) as in Backbone's documentation examples. (Julien already commented this on the OP, I'd like to give an explanation why I think he is right) It's probably best to use Collection in exactly the way it was intended: as a bundle of models.
