For defining objects from which objects in your form can be based.

In the 'old' days, you could base a new form on an old form by copying or referencing. Copying was a copy, no linkage maintained, and referencing maintained linkage. Unfortunately, to get this referencing to work you had to have the 'base' form open in your builder when you opened your 'referencing' form. Object libraries only have to be in your 'path' when you open your form. The object library is also used when you do a batch compile whereas the reference form was not used during a compile [correct me if I am wrong].

This means that you can have multiple object libraries, with the same name, in different directories, to give you different behaviour depending on which environment the forms were compiled. This last one is tricky and can be a nightmare to debug. Only to be used by control freaks.
