Where can I learn more about a specific material, technical concern, or other conservation issue?

The Getty Conservation Institute maintains a robust and updated collection of resources on a variety issues facing the fine art conservation field. It can be a good starting point if your goal is to better your conservation knowledge or prepare for the treatment of a specific artwork.  
Generally, when considering new materials it behooves the artist to thoroughly research the long-term stability of the material and ensure that it is suitable to prolonged outdoor display. This is particularly important for artworks that will be installed in highly trafficked areas or in communities with extreme weather concerns. If the artist or administrator has any concerns about the long-term suitability of a material, fabricating technique, or anchoring strategy, those concerns should be raised immediately, and may require consultation with a manufacturer or trained fine art conservator.
