Academic pricing is for students, researchers, and educators at accredited institutions. Business pricing is for everyone else, with a higher included monthly quota and larger collections.
What Counts as a Lookup?#
DOI lookup: 1 lookup
ISBN lookup: 1 lookup
Reverse lookup (paste text): 1 lookup
Re-looking up a DOI or ISBN already in your collection: FREE
Manual entry: FREE (no lookup)
Re-formatting in a different style: FREE
Save citations to a collection and look them up again any time at no cost. Papers stay free to re-lookup as long as they remain in a collection.
Batch and Collection Operations#
Batch formatting and DOI verification use the normal lookup quota. Signed-in Free accounts can batch-add collection entries and import BibTeX/RIS files. Merging collections and moving entries between collections require an Academic or Business plan. Collection sharing is available to every signed-in plan.
Paid Utility Tools#
Citation key generation, bibliography normalization, and journal abbreviation expansion require an Academic or Business plan.
Trial#
The Academic plan includes a 7-day free trial. Business checkout requires payment when the subscription starts.
