Collections

Collections that group all the volumes of a series, all the years of a periodical, or monographs united by common topics covered. They are made up of several volumes and have a price significantly lower than the sum of the prices of the individual volumes. Pay attention: in the case of series or periodicals, some published volumes may be missing, but they are currently out of print and therefore do not appear in the collection. To take advantage of the purchase, a certain number of volumes are included in the cart, others can be added as an option.
