Apparatus and method employing a programmable computer for providing a list of data items corresponding to geometrically describable materials based upon a profile specified by a user includes, storing data items in a data base. Each data item includes geometrically descriptive terms and trading parameters identifying characteristics of an item offered for sale by an advertiser. A profile is generated by a user which includes geometrically descriptive terms and trading parameters identifying characteristics of an item sought for purchase by the user. The profile identified by the user is compared to each data item stored in the data base and data items are identified which match the profile. The data item identified are provided to the user in accordance with the user's specific delivery instructions.
