Record collections boost a blossoming music library, or enhance an already impressive one. Budding enthusiasts--both listeners and composers-- would do well in educating themselves though record collections. It's like reading Classics in literature so you could understand the craft and write your own.
The same applies to music. Album collections are arranged by genre, era, and origin, making it easy to seek out any sections one hasn't explored yet, akin to pointing at a map and going there.
