You can transport books on any vehicle – everything will depend on the size of the library itself. If there are a small number of boxes of books, they can be transported in the trunk or interior of a car, as well as in a trailer. However, books are usually transported in a van https://www.flashmoving.net/household-movers/apartment-movers/ along with all other things. In this case, to avoid deformation of books, you should not stack many boxes with them on top of each other. For the same reason, other heavy objects should not be placed on the boxes themselves.
