Simon's personal library covers a broad range of primary and secondary sources relating to the history of architecture, landscape design, construction technology, local history and popular culture.  The collection is particularly strong on Australian architecture of the post-Second World War period, and includes substantial runs of trade, professional and popular journals, directories, catalogues, pamphlets and other ephemera.

The library includes a number of items that were formerly in the possession of noted twentieth century Australian architects and firms, including
Gordon Banfield (of Bogle & Banfield), Charles J Christopher, Babs Delaney, Stephen Dorling, Alec Eggleston, Godfrey Spowers Hughes Mewton & Lobb, F Bruce Kemp, George Mitchell (of Mockridge, Stahle & Mitchell), Keith Reid, K W Shugg (of Bush, Haslock, Shugg & Moon), Harry Winbush and Yuncken, Freeman Brothers, Griffiths & Simpson.  An extensive run of the journal Architecture & Arts was purchased from a former client of Robin Boyd.  A list of these books, arranged according to their provenance, can be viewed here.
