A framework for the evaluation of chemical structure databases

Access to desk-top structure and reaction databases through applications su ch as Chemical Abstracts' SciFinder, MDL's Beilstein CrossFire, and ISIS Re action Browser has led to changes in information seeking habits of research chemists, the impact of which has implications when database purchasing de cisions are made. A semiquantitative assessment is proposed which takes int o account key aspects of structure and reaction databases. Assessment crite ria are identified which can be weighted according to an organization's inf ormation needs. Values are then assigned to criteria for each data source, after which a formula is applied which leads to an indication of the relati ve value of systems under consideration. The formula takes into account the cost of database products and also the incremental benefit of adding a new system to an existing collection. This work is presented as a generic appr oach to the evaluation of databases and is not limited in scope to only str ucture and reactions databases.
