An argument for favoring real books instead of omnibus textbooks in the classroom:
On the other hand, a solid and inviting bookshelf containing a growing subject-focused set of books, magazines, monographs and web links offers depth and breadth typically unavailable through textbooks. This mini-research library sets a tome (ahem!) for the possibility of personally surprising adventures and small group discoveries of the talented people, magical concepts, fascinating discoveries and important events that make up most of the reasons for teaching a subject in the first place. The kids can and will help build this treasure if we just ask.
