One of the challenges of the last few months has been accessing materials that my library does not own. With the majority of libraries being closed, we have not been able to borrow these materials from the usual suspects.
When looking for government publications, one useful source is the Government of Canada Publications website which includes a catalogue of over 502,000 publications and which provides online access to more than 381,000 government publications.
The website offers an advanced search feature which allows you to limit your search by such criteria as department, language, and publication date. The collection includes PDFs of older publications that have been digitized; for example, the 1930 publication “Poultry house construction, with general and detailed plans” is available for your reading pleasure.— Susannah Tredwell
