If you've got a library card, you have access to all sorts of Databases. Most public libraries in Australia (to the best of my knowledge) will give you free access to the Library edition of Ancestry. And at the Redcliffe, Strathpine, Caboolture and North Lakes branches of the Moreton Bay Region Library service you also get access to Find My Past.
SLQ eResources gives you access to The Age Library edition and Sydney Morning Herald 2006-2017 as well as the Sydney Morning Herald archives (1955-1995), British Library Newspapers 1800-1860, Irish Newspaper Archives (depending on the title - anywhere from 1738 - present), Oxford Dictionary of National Biography, Times Digital Archive 1785-2010 and Who's Who in Australia.
The National Library of Australia eResources gives you access to American National Biography Online, Bibliography of British and Irish History, British Library Newspapers, China Core Newspaper Database, Dublin Castle Records 1798-1928, Early English Books Online, Economist historical archives 1843-2013, Eighteenth Century Collections Online and Eighteenth Century Journals, Gerritsen Collection: Women's History Online 1543-1945, Irish Newspaper Archives, Japan Chronicle, 19th century British Newspapers, 19th Century UK Periodicals, Punch Historical Archive 1841-1992, 17th & 18th Century Nichols Newspaper Collection, Illustrated London News Historical Archive 1842-2003, Sunday Times Digital Archive 1822-2006, The Telegraph Historical archive 1855-2000, The Times Digital Archive 1785-2011, 17th & 18th Century Burney collection newspapers, UK Parliamentary Papers. There's lots more but you get the idea.
D is for dictionaries....all sorts....
I have the Penguin Dictionary of Surnames.
I have the Dictionary of Old Trades & Occupations by Andrew & Sandra Twining
I have A Glossary of Household, Farming and Trade Terms from Probate Inventories by Rosemary Milward
I have the Oxford Companion to Local and Family History which has essays and then a kind of dictionary in it with different subject headings.
I have the redoubtable The Family Historian's Enquire Within by F.C. Markwell & Pauline Saul - a wonderful dictionary of terms and phrases and acronyms you are likely to encounter in your journey.
I've got French, German and Latin dictionaries.
There are of course topographical dictionaries of England, Ireland, Scotland and Wales to name a few. I don't have those. They would be nice to add to the collection.
I would also like a dictionary of medical terms but perhaps the very scary Blacks Medical Dictionary that I have will do for the moment. If you want a good fright look up Housemaid's Knee. On principle I don't do much housework having seen the gruesome effects. My knees weren't particularly attractive to start with - no point in making them any worse.
