Where it leans in its goals depends on the type of library: a national, reference, or research library will likely have preservation as a foremost goal (the first and second especially, but a research library needs to preserve primary and secondary sources no matter how old they are, unless they get punted to a specialised reference library), while a public or academic library will be more concerned with having resources patrons are generally interested in.
