Put a pasted reference list into alphabetical order

Sorts a pasted reference list into alphabetical order by first author and flags entries that look like duplicates.

Runs entirely in your browser. Nothing you paste is uploaded, stored, or sent anywhere.

How it works

Paste your list with one reference per line — or with references separated by blank lines, which the tool also accepts. Each entry is treated as a single block of text, and the leading characters up to the first period or opening parenthesis are used as the sort key, which for most styles is the author field.

Sorting uses your browser’s locale-aware comparison, so accented characters such as Ö and Ø fall where a reader expects rather than at the end of the alphabet. Leading articles are left alone, since styles differ on whether “The” is ignored in a title-led entry — if yours ignores it, check those few entries by hand.

Duplicate detection is approximate. Entries are compared after lowercasing, stripping punctuation, and collapsing whitespace, and near-identical pairs are flagged rather than deleted. Two versions of the same source with different page ranges or a DOI on one and not the other will be shown side by side for you to decide.

This is a formatting utility, not a citation generator: it reorders what you give it and never edits a reference, changes a style, or looks anything up. All processing happens in your browser.

Why it matters for academic writing

Reference lists get assembled from several drafts, several co-authors, and several sessions, and they arrive out of order with quiet duplicates in them. Sorting and deduplicating before submission catches the mismatches that a reviewer would otherwise catch for you.

Questions about the reference list sorter

Are my references uploaded or stored?

No. Sorting and comparison happen in your browser; nothing you paste leaves your device and nothing is saved between visits.

Does it work with numbered styles like IEEE or Vancouver?

Alphabetical sorting is the wrong operation for those styles, since the order is set by first appearance in the text. The duplicate check is still useful, but do not reorder a numbered list.

Will it fix formatting errors in my references?

No. It reorders entries and leaves every character inside them untouched. Style formatting is a separate job, and doing it silently here would risk corrupting entries you had already made correct.

What if my references span multiple lines each?

Separate them with a blank line and the tool will treat each block as one entry. A list where every reference runs across lines with no blank line between them cannot be split reliably.
