Bibliography

Literature on the subject of stone and all its aspects would fill entire libraries ... Therefore, no attempt will be made here to produce a comprehensive list, or even anything approaching it. The aim is to provide a few suggestions concerning works on certain subjects. The focus will naturally be on stones from the Walloon Region, whenever this is possible. Most of these publications may be found in well-stocked libraries – many are unfortunately out of print and cannot be obtained from bookshops. The books themselves often contain detailed, even exhaustive, bibliographies; we have used an asterisk (*) to mark out those of particular interest in this regard..
