libreoffice impress presentation reference / bibliography manager

Is there a reference manager (i.e. EndNote/Mendeley) extension available for libreoffice impress presentation software? It is my understanding that endnote does have an extension available for microsoft powerpoint. I have installed the mendley extension for libreoffice writer, but I haven’t had any luck doing the same on the impress presentation software. Does endnote have an extension for libreoffice impress presentation software?

Not quite sure whether you are asking for how to insert notes into your presentations, but if yes, then just load your Impress presentation → View Menu - > Notes Page → under your slide a box with the text “Click to add notes” will appear → click on it and edit it. It’s pretty much easy. As a paperwriter did it multiple times and everything works. For more check this OpenOffice documentation

No, this question is about how to cite a publication in LibreOffice Impress with the help of software such as Mendeley (Comparison of reference management software - Wikipedia), which would mean that you don’t need sort, number, copy-paste or type the title of the publication, the names of the authors etc. manually - which is very wearysome. Anybody knows good advice on that?

This article on the bibliography manager is very informative. It actually proffers a review of each of the records. Articles like this can help students and other peoples to get familiar with various types of presentations in LibreOffice.
