There are inconsistencies within the one-column layout and a variety differences with the two-page layout:
1) Hyperlinks in "Selected Articles" are not shown by different color 2) The notes in the "Notes" section also have a strange color layout: the note itself (which is a hyperlink) is normal black but the additional information, if any, is printed in grey. 3) In the "Further Reading" section: here as well there is no difference between regular text and hyperlink. And some other color differences, most involving hyperlinks.
