hard to explain...
I'm working for french association of archaeologists. They have two distinct libraries :
1- is a public library of scientifics books wich can be lend or buy (for some), at this time it is manage by a Filemaker DB with informations like "Row" - "Lane" - authors - date and classics...
2- is a private library with report about archaeologist site and activities of the association. For this informations are differents : name of the site - location - operator - date - period - author .... also manage by a filemaker DB.
So i wanted to create a categorie for "1" (books) and an another for "2" (report). But i need to be able to display different informations.
