A government library can probably do this under the government use provisions in the Copyright Act (section 183).
A library in an educational institution may also be able to do this under Part VB of the Copyright Act.
For other libraries, such as a public and corporate libraries, options include:
• circulating a list of contents with your own abstracts (rather than copies of the documents),
• getting a licence from CAL – this allows some digitisation of published materials for internal purposes. http://www.copyright.com.au/Licensing_schemes.aspx
