Update Fri May 6th : access to all ebooks has been fully restored. Thanks for your patience, and apologies for the incovenience.
We are currently having some issues with one of our servers. This means that instead of accessing content on the DawsonEra e-books site directly, we are getting warning screens about accessing the site.
We are working on the issue as a high priority.
In the meantime users can still access Dawson content via the following screenshot. Please use Chrome for best results (and click 'Advanced' to see the option to proceed to the site).
