The ability to change the text frequently is one reason why we have chosen to go with “print on demand”. The other is that it has a lower environmental impact as supply matches orders.
The chapter on ISO 50001 has been completely updated as the standard has moved from 50001:2011 to 50001:2018. There have been other updates and corrections throughout the text including checking and updating all the web links in the 800+ bibliography at the end of the book.
The free PDF has been updated as well as the print editions. Please do download the free PDF rather than buy a print version – not only is that more resource efficient but you will always have the up to date version! However, if you absolutely insist on buying a print version, then please do order it through this site.
There have been some price increases in the print version, as follows:
- The paperback is increasing from £59.99 to £74.00 (US$79.99 to US$99.00)
- The hardback is increasing from £79.99 to £89.00 (US$109.99 to US$129.00)
The price rises are due to an increase in printing costs but mainly because third-party vendors require a larger margin than I have been previously willing to offer, in order to list the book in their sites/stores. I have held the prices as low as possible – this is not a money-making project – but I have reached the conclusion that I do need the book to appear on sites like Amazon and bookstores, if it is to reach a wider audience.
Please continue to send me suggestions for improvement and errata – I really appreciate these.
