We have published updated editions of the Street Index for well over a hundred years. This is probably the earliest edition that includes a total of 1761 lots mainly in Victoria. The Street Index provides easy reference for finding the street and house number information of all leased lots and vice versa. Of the published 32 editions, 25 were published before the war. The first post-war edition was published in 1956, 19 years after the 25th Edition. Owing to the vast number of changes which had taken place, the revision took over 2 years and involved the scrutiny of nearly 70,000 Memorials and a physical check of every street. Since the 28th Edition (1968), the Land Office published the Street Index in loose-leaf form and provided successive additions and alteration by issuing noters-up at six monthly intervals. From the 31st Edition (1999) onwards, it was published annually in the form of CD and replaced the tradition bulky volumes of this index. Since the 43rd Edition (2011), an online version of the Street Index has also been uploaded to the Land Registry’s website for free browsing. Users can now search data more speedily and conveniently through the Internet.
