A stamp indicating the National Library's ownership is affixed in the book. The stamp also has space for the year of purchase, the classification of the book, the vote used to purchase it, and finally its location, that is, whether it is earmarked for Mahalapye or Serowe. Most importantly the stamp identifies the book with the Book Box project. That way if it is left in any library or classroom the finder will know where to return it to. Colour-coding is the process where the books are classified.
Classification means put together according to subject content.
The boxes of books are sent to the schools at the beginning of each term. Each box is given a different number. Towards the end of each term the boxes are collected. Any needing repair is seen to and at the beginning of the following term the boxes are sent to different schools. The numbering is the basis for the rotation.
