Answer:
Femi's possession of the collection satisfies the perfection requirement because it puts a third party like Orin on notice of Femi's interest in the property.

The Uniform Commercial Code are a set of guidelines for all states in the USA that pertains to sale and purchase of goods.
Under these guidelines the borrower must have actual possession of collateral that puts everyone on notice that the borrower has a security interest in the collateral.
In this case Femi already has possesion of the books and satisfies the perfection requirement because it puts a third party like Orin on notice of Femi's interest in the property.
