The DGG does literature research in the field of glass both in-house and in external databases.
Since its foundation in the year 1922, DGG has gathered information about literature on the topic of glass and built up its own literature documentation. Thus, a collection of 60 000 references exists that is enlarged continuously and forms an essential basis for literature research.
Since 1994, DGG has also been able to search R&D results and publications in international on-line databases in order to guarantee a more comprehensive and fast supply of information.
