A British parliamentary paper on the treaty of commerce and navigations, which was signed in Kanlıca, a prominent neighbourhood on the suburbs of Istanbul, in 1861, was printed in London in the same year.
We could only find 3 institutional examples (Simon Fraser University Library, San Diego State University Library and UCL) with a possibility of some of them being e-books. Not in the British Library.
