In Mendeley, references are organized into Collections.
Your account automatically has the following collections:
The collections you have created are displayed in Collections.
Create a Collection by selecting New Collection button in the left hand navigation panel. Give the collection a name.
There are two ways to move references to the collection.
1. Drag and drop them.
2. Select references from the list. An action panel opens to the bottom of the page. Select Organize, then Add to Collection. References are listed in your collection and also in All references.
You can collect references to Favorites by clicking the star next to the reference.
You can delete unwanted references from your Mendeley account by selecting the reference, then the Delete button at the bottom of the page. If you want to delete a reference from one collection only, select the reference, then click Organize and Remove from Collection. The reference will remain in other collections as well as the All references collection.
Deleted refences are moved to Trash. You can Restore references in Trash or Delete permanently from Mendeley.
Mendeley Reference Manager or Mendeley Web do not currently have a functionality for searching duplicate references. You can sort references by Authors or Title, to make it easier to find and delete duplicates.
The free version of Mendeley offers 2 GB of space. For most users that is sufficient. You can check the remaining space by clicking your name on the upper right corner, then Settings and Subscription.
You can find and delete duplicate references in the Duplicates view.
Use the View function to show or hide information in the reference list view. Table row settings determine the amount of data visible in each row. Manage columns to show or hide columns (Author, Year, Title, Source, Added, File, Unread, Favorite) and order them.
Additionally, you can arrange the references in ascending or descending order based on the desired column.
