I've said this ad nauseam no doubt, but: my early musical education (learning to read scores, getting to know the repertoire) was largely the result of my weekly visits to the Swansea public library, which had a fantastic selection of LPs, everything from organum to Kagel (who was next to unknown in the UK in the 1970s I would say) and a reasonably wide selection of scores. The breadth of listening and learning I was able to do there would be impossible now even in the central public libraries of the larger cities.
Substitute London Borough of Harrow for Swansea, and that's a pretty accurate description a large part of my early musical education too.
