Which London publisher issued the first edition of Dracula?

Archibald Constable and Company issued the first edition of Dracula.

The London publisher released Bram Stoker's novel in May 1897, probably on or about 26 May. The first edition was bound in yellow cloth with red lettering and sold for six shillings. It was initially advertised under the title Dracula after a late change from the working title The Un-Dead, a detail visible in surviving publishing material.

Archibald Constable and Company was a major British publishing house with roots in the firm founded by Archibald Constable in Edinburgh in 1795. Its list included important literary authors, and its connection with Stoker placed Dracula within the established Victorian book trade rather than the later mass-market horror industry. A common mix-up is naming Constable's later imprint, Constable & Robinson, as though that were the original company name. Another is choosing William Heinemann or Macmillan, both prominent publishers but not the house that issued Dracula's first edition.
