BibSonomy allows you to import bookmarks and publications from other programs. The internationally standardized data format that is supported by all major bibliographic management programs is called BibTeX. The import takes place in two steps. First, you have to export the publications from your previous reference management software, then you have to import the BibTeX data into BibSonomy.
Advice: Please note that apart from the different programs there are also different program versions, so there may be two or more ways to export data in one program. Therefore you should try all the options if necessary.
