Part of the confusion is likely how terminology is used. In other language systems, for example in C, you would normally have separate source files for each of the functions (in cases where you have interrelated functions that are *always* used together, you might combine them in a single source file). Compilation of individual source files generate individual object modules (e.g. .OBJ files). The librarian software is then used to construct the separate library files (which is basically a convenient method of gathering related program modules together into a single location). The linker software is used to combine the specified individual object modules, along with any required ones from the libraries to combine to create the final load module (e.g. .EXE file).
In VFP, "function library" is used, wouldn't be considered a real "library" in the same sense. It refers to collecting items at the source level that produces a single "chunk" that can't be broken out into parts. If I'm not mistaken, the entire class library is brought in -- much like a single PRG file. The upshot of this is that if you want to minimize the "footprint" your program, you have to separate the components into individual parts at the source level. This means you probably want to limit the number of classes per VCX to only a handful at most (that is if these are classes that are always going to be used together), and function libraries should be broken up into individual PRGs. Unfortunately the result of this would be that you could end up with a large number of individual PRG/FRX, and VCX files in a single project, which is rather inconvenient. For the convenience of having individual functions and classes into only a handful of "library" files is eventual bloat.
Granted, if you look at earliest example of use of term "library" it typically meant a group of routines that were brought in (in their entirety). Likewise the original term usage of "compiler" is more like the modern usage of the term "linker" -- though this usage was back when most programming was done at the machine code level rather than HLL.
