What it does

Written by AI from the README

Finds missing DOIs, and abstracts, by searching Crossref with an item's title, first author and year, accepting only close title matches. Runs on selected items, a collection or the whole library, optionally for new items. No API key needed.

Many records lack DOIs, and adding them by hand is slow. This fills them in bulk, with a configurable match threshold and request delay.

What you'll need

Detected automatically

We haven't detected any setup requirements. That isn't the same as none: check the developer's README.

Your rating of DOI and Abstract Finder v0.0.3

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
