Career
On his death, his collection became the nucleus of the Alexander Turnbull Collection, initially housed in his house on Bowen Street opposite Parliament Buildings but as of 1987 housed with the collections of the National Library of New Zealand. In 1913, shortly before his death, Turnbull had presented his Maori and Pacific artefacts to the Dominion Museum (now Te Papa). By the time he returned permanently to New Zealand in 1892, he was already collecting books
His particular interests were New Zealand, Pacific exploration, Scottish history, English literature, John Ruskin, and, particularly, John Milton.
He had a standing order with London bookseller Bernard Quaritch, which was regularly updated to include more subjects. After his death his collection contained approximately 55,000 books, as well as manuscripts, photographs, paintings and sketches (the artefacts having already been given to the Dominion Museum).
The collection is no longer housed in his purpose-built house (which is now in the care of Department of Conservation and known as Turnbull House), but in the same building as the other collections held by the National Library. Turnbull"s Milton collection continues to be added to, by purchase and donation.
A number of significant additions were made in the 1970s.
