DOI Link Generator
Clean a single DOI or switch to extraction mode to find unique DOI identifiers inside pasted reference text without uploading it.
How DOI normalization works, and what it cannot prove
A DOI has a prefix that starts with 10. followed by digits, a slash and a registrant-defined suffix. Lynara accepts a bare DOI, a doi: label and older dx.doi.org links, then normalizes the result to the https://doi.org/ form.
Worked example: the input “DOI: 10.1037/0003-066X.59.1.29.” loses its label and trailing period and becomes https://doi.org/10.1037/0003-066X.59.1.29. In extraction mode, the same DOI pasted with different letter case is returned once.
Normalization checks the identifier format, not the bibliographic match. A DOI copied from a PDF can include line-break artifacts or surrounding punctuation, so open the normalized link and confirm that the title and source are the work you intended to cite.
Some DOI suffixes contain plus signs, balanced parentheses, angle brackets or an escaped hash symbol. Extraction now keeps these characters together, while the resolver link encodes a literal # as %23 rather than treating it as a page fragment. If a PDF breaks a DOI across lines, still compare the full identifier with the publisher record.
Crossref recommends the https://doi.org/ display form. Citation styles can still differ in how they present DOI information, so follow the style guide required by the assignment.

Privacy: bibliography and DOI utility inputs are processed locally in your browser and are not sent to a citation-processing backend.
Formula
canonical DOI URL = https://doi.org/ + normalized DOI; extraction finds DOI-shaped identifiers then de-duplicates normalized values
Example
doi: 10.1000/xyz123 becomes https://doi.org/10.1000/xyz123; extraction can collect several DOI strings from a pasted bibliography.

Questions
Does Lynara look up the DOI?
Not in this tool. It normalizes or extracts DOI identifiers locally; use a citation generator with DOI import when you need source metadata.
Can I extract several DOIs at once?
Yes. Switch to extraction mode and paste reference text; Lynara returns unique DOI-shaped identifiers it can normalize.
