Hi Peter, corrected. It was necessary to change the template from book to encyclopedia ☺ Regards -- Bernhard From: Peter Easthope [mailto:petereasthope@gmail.com] Sent: Monday, November 30, 2015 4:54 PM To: oberon@lists.inf.ethz.ch Subject: [Oberon] Fault in https://en.wikipedia.org/wiki/Oberon_(operating_system). Hi,   When https://en.wikipedia.org/wiki/Oberon_(operating_system) is opened for editing, the wikimedia software complains that a reference has two titles.  These are "Oberon - The Oberlooked Jewel" and "The School Niklaus Wirth - The Art of Simplicity".  Only the second title is  displayed under References.  Currently it is reference 25 and the number will change when a preceding reference is added. I don't know which of the two is preferred.  Someone with a more direct interest can make the correction.   Regards,                       ... Peter E. -- Telephone 1 360 639 0202 or +13606390202.
