In BibSonomy, there are several pages where bookmarks and publications are displayed in two columns (e.g. on the homepage or on a user's page). On these pages, you are able to sort the bookmarks and publications.
For simple sorting, just click on the gear symbol in the respective column. The options are listed under "sort".
criterion: You can sort entries by date or by title (alphabetically).
order: Choose between ascending order (oldest date - recent date or A - Z, respectively) or descending order (recent date - oldest date or Z - A, respectively).
Note: Advanced sorting is only available for publications.
Advanced sorting is taking place by adding one or more parameters to the URL (see URL syntax). The following parameters are available:
sortPage - How is the list sorted?
sortPageOrder - order of sorting
Sort by year (sortPage=year) ascending (sortPageOrder=asc) and remove all duplicates (duplicates=no).
