Hi All,I have a researcher here that is interested in metabolic maps, ones like the Roche Biochemical Pathways and maps showing biochemical systems more generally. We haven't historically collected these materials.If anyone knows of a specific collection that has a large set of such maps or tends to collect these materials, please let me know. I would love to be able to point this researcher in a useful direction.best,Dave--David WeimerLibrarian for Cartographic Collections and LearningHarvard Map Collection, Pusey Library, Cambridge MA 02138
