Are Biblioteca lessons different from "normal" Garbanzo lessons?

At the Premium subscription level, Garbanzo offers a variety of ways that teachers can assign lessons and that students can read lessons on Garbanzo.

The Biblioteca offers teachers a way to "unlock" lessons for their students so that their students can choose what they want to read and how many times. The Biblioteca uses the same lesson catalogue that is utilized for all assignments. At the Premium Subscription level, any lesson in the Garbanzo catalogue can be sent to students as a single assignment with a due date or as an unlocked option for them to choose to read in their Biblioteca.
