On Thursday there was a small catastrophe on the website, in which we managed to delete over 2000 books from the site. We were able to get the books back on there, but our ecommerce system was labouring to catch up to make the books available for purchase.
The good news: Physical books are back and can be bought as normal.
The bad news: eBooks are lagging behind and are temporarily unavailable.
We are working hard to resolve this and will continue to give updates on the situation. We'd also like to thank you all for your continued patience.
Update: Unfortunately these issues are also having an impact on our membership system which is experiencing issues, again we are working flat out to try to come up with a solution to this.
