The photograph of the SSC library was probably taken about 1900 and probably at the time that William Black gave up the office of Librarian. He had been admitted to the SSC Society on 23 June 1871. He appears to have worked in his own firm at 38 Hanover Street, Edinburgh. He held the post of Librarian for 26 years. He supervised the removal of the library to the new hall and prepared a catalogue and also contributed several articles on legal books. The photograph seems likely to be an implied statement of triumph in that a difficult task had been completed successfully.
