This is a collection of inividual fact cards,by I.M.P publications they would send you 2 packs containing 12 cards each once every other month, and occasionally send you a nice binder, the first shipment came with a few binders a few packs of cards and all the section seperators as all the cards go into its own section and all the cards are numbered. Each card folds out in three and theyre packed full of facts. Unfortunately this collection is out of print and I ve never finished the collection so I got alot of missing cards although I do have alot of cards in the binders. This one is great to add to the bookshelf.

Pros: lots of facts, easily organized

Cons: out of print,

Used these a lot esp. when I worked at an exotic park. They provide quick information about ecology of animal.

Pros: quick info

Cons: none
