What Is Mendeley and What Is It Used For?
Mendeley is a reference manager and academic social platform owned by Elsevier. It is used to collect and organize research papers, store and annotate PDFs, generate citations and bibliographies in word processors, and sync a personal library across devices. It is aimed mainly at researchers, students, and academic authors who need to keep track of sources and cite them consistently. Its distinguishing feature compared with a plain reference manager is the combination of library tools with a research community and discovery layer. Mendeley has a pricing page, so at least some plans or features are tied to payment; the available source material does not specify what is free.
The two sides of Mendeley
Mendeley is best understood as two products in one:
- A reference manager. You build a personal library of references, attach PDFs, and insert citations into documents.
- An academic network and discovery tool. You can follow research areas and other researchers, and use the platform to find and discuss papers.
The reference-management side is what most people use day to day. The social and discovery side is what separates it from tools that only format citations.
Core uses
Managing references and PDFs
You add references manually, by importing files, or by pulling metadata from a PDF. Each entry can carry the usual bibliographic fields — authors, year, title, publication, DOI — plus tags, notes, and folders. PDFs can be stored in the library, read, and annotated with highlights and comments. This is the part that replaces a folder of loosely named PDFs with a searchable, tagged collection.
Generating citations and bibliographies
Mendeley integrates with word processors through a citation plugin. The typical flow is:
- Install the plugin for your word processor.
- Place the cursor where the citation belongs.
- Search your Mendeley library from inside the document and select the reference.
- Insert the citation; the bibliography updates automatically.
- Change the citation style (for example, a journal-specific style) and let the document reformat.
The expected result is a document whose in-text citations and reference list stay consistent with your library, so you do not renumber or retype entries by hand.
Reading, annotating, and syncing
Annotations made on a PDF are tied to that document in your library, and the library syncs across devices through a Mendeley account. The practical benefit is starting a paper on one machine and continuing on another without emailing files to yourself. Sync also means your library is backed up rather than living only on one hard drive.
Discovery and community
Because Mendeley is also a network, you can browse research areas, see what others are reading, and follow activity around papers. This is useful for keeping an eye on a field, but it is a secondary function for most users — the library and citation tools are the reason people stay.
Who it is for
| User | Typical use |
|---|---|
| Students | Collecting sources for essays and theses, formatting references |
| Researchers | Organizing a large PDF library, citing across multiple papers |
| Authors | Managing references for manuscripts and switching journal styles |
| Groups | Sharing references and PDFs with collaborators |
How it differs from a plain reference manager
A basic reference manager stores and formats references. Mendeley adds:
- A public-facing profile and research network.
- Discovery features for finding papers and research areas.
- A recommendation and social layer around the library.
If you only need to format citations and never want a public profile or social features, that extra layer may be unnecessary. If you want your reference tool to also be a place to find and follow research, the combination is the point.
What to check before committing
- Pricing and plan limits. Mendeley has a pricing page, so check which features and storage limits sit behind a paid plan rather than assuming everything is free.
- Word processor support. Confirm the citation plugin works with the word processor you actually use.
- Import and export. Check that you can import your existing library and export it later, so you are not locked in.
- Collaboration needs. If you share references with a group, verify how sharing works on your plan.
The fastest way to judge it is to import a handful of real references, insert two or three citations in a test document, and change the style once. If that flow fits how you write, the rest of the platform is a matter of preference.
