Not a value list but separate records?

Can somebody help me with the following?

I'v got two databases:

1. One CD-file (with track-description)

2. One Library-file (with info about a library)

What I would like is to have is an index (in the Library-file) of all the CD's a Library contains.

In this example I would like to create only 5 records (CD's: 1001, 1002, 1003, 1004, 1005) in stead of 587 (CD's + Tracks) for the library called "1000 SERIES THE GENERAL" (which is a record in my "Library-file"). So I like to see an index of which CD's are in this particular library without tracks and without duplicates.

But when I add new data of a new CD in the CD-file, for instance 1006 with 75 tracks, I would like to automatically have just one new record (1006) added to the "1000 series-record" in the Library-file. (For other functions it is important that this are separate records and not a value list!)

Is this possible?

Thanks for your help in advance.

Greetings,

Richard
