A Library database, also sometimes referred to as a Code Library, Code Db or Reference Library, is a standard Access database (which can be compiled to secure it from prying eyes) that enables one to create an easily deployable, reusable, maintainable library of objects and code to implement within any other database. At one end of the spectrum, you have a pattern where all repeated code is in a library. You'll find success somewhere between the two. Similarly, many subroutines and functions are intended not only to reduce code in a single application, but also to be "black boxes" that can provide some service to multiple applications. If you do this, you will realize that for code generation, in some cases, even if you specify that you want a reusable function, as shown above, you might not get a reusable function: So the flexibility that you gain by model reusability, comes with the tradeoff that different functions can be generated for each use of the library subsystems. Here are some reasons not to use code libraries. In particular, I can see the usefulness of one or more utility libraries. Easy to find the upside here.
