I've had great luck finding 'Victorian Era' books on http://books.google.com/ E.g., Maxwell's collected works, Treatises on Determinants, etc. You might want to download as many of these as possible, as you never know when Congress will 're-copyright' all this stuff yet again (so much for the Constitution's 'limited time' clause). Luckily, a terabyte of memory is now < $100. At 08:32 AM 5/10/2013, Fred Kochman wrote:
I miss all those Victorian era (or slightly later) math books that Dover once published, not always so rigorous but full of fascinating formulas and examples, and all those exercises culled from old tripos exams and the like. They would be out there forever, so I thought, so I could buy any of them later, any time I felt like it.
