And also, if you think about it most, a lot, an awful lot of key zoological literature, and I’m talking about books mostly were written during the early years of those, of those scientific societies in London. So not only London Zoo, geographical society, the ones I’ve already, people like the Royal Botanical Society and so on, so long before there were, I mean there was certainly a few Philadelphia, one or two other large city institutions in America that were starting in the mid 18 hundreds anyway, but probably at the time didn’t have access to some of the book collections that were around and certainly didn’t have access to a lot of the people that actually wrote those books. So people like Darwin, Darwin had a quite a strong relationship with, with the London Zoo Society and many, many authors, zoologists scientists at that time had, you know, had a relationship of some form with the new, what was then the new zoo. And so the founding of a library really became, you know, almost a necessity for that sort of scientific institution. So, and that, that of course over the years then that was built on because a a we had a lot of, a lot of those volumes contributed. The zoo was buying, you know, it was obviously buying volumes at one time. So it’s, it, it’s largely, it’s largely a matter of age really. And how long and the, and the sort of people that were associated with, with the Zoo society, you know, early, you know, early in the 19th century There starts to be more cooperation between zoos.
