ProQuest have advised there are new eTextbooks available for purchase for 3-user perpetual, DRM access on ProQuest eBook Central.  The list is available here.  Check out the individual worksheet tabs at the bottom to see the different choices.  Of particular note is that some Wiley eTextbooks are now available for sale at $US900 per title.  In some cases we currently have multiple copy holdings.  Please email acquisitions@libr.canterbury.ac.nz if there is any interest in any of the titles on offer, within the next week if possible so we can see what we may be able to purchase this year.
