This page contains links to online mathematical references, portals to the world of online journals and preprints, and some good online textbooks.
General mathematical references
 MathWorld is "the web's [selfproclaimed] most extensive mathematics resource" hosted by Wolfram Research, the makers of Mathematica. It is a mathematical encyclopedia containing precise articles about almost any piece of mathematics you are likely to come across in your studies.
 MathSearch is a mathematical search engine that searches over 200,000 documents on Englishlanguage mathematics and statistics servers across the web.
Mathematical journals and preprints
 The University of Melbourne's Find Information page has an "Electronic Resources" search, that includes a large number of online journals. Through this site (and using your library barcode), you can access many journal articles online.
 arXiv is a freely accessible archive of eprints in physics, mathematics, nonlinear science, computer science, and quantitative biology.
 MathSciNet has reviews of most mathematical papers, books, and conference proceedings. It is a subscriptiononly service but can be accessed via the University of Melbourne's Mathematics and Statistics resources site.
Mathematical Tools
 The Integrator is an online symbolic integration tool powered by Mathematica. Never let a nasty integral get in your way again!
Online textbooks
A good way to get your head around difficult maths is to read what lots of different people have written about it. These are just a few of the good books that are freely available online.
 Abstract Algebra: The Basic Graduate Year is a readable algebra text with exercises and solutions. The first 6 chapters cover almost all of the material in 620321 Algebra.
 Introduction to Probability is an introductory probability text that covers almost exactly (but in a somewhat different order) the material in 620201 Probability.
 The Calculus Bible is a careful introduction to onevariable differentiation and integration and sequences and series. It is ideal for students of 620121/141 and 620123/143 who don't believe anything without proof (and anyone else looking for more exercises).
 generatingfunctionology is the book on generating functions. It is aimed at advanced undergraduate/honours level.
