We are excited to be working with Marshall Cavendish to offer their eBooks as well as their digital reference content that lets you build your own reference library. They offer their content (spanning history, health, business, etc) both as a database as well as in eBook format, and the pricing is very highly discounted.
We also have a trial available. To access the trial of Marshall Cavendish Digital, email me for login details.
