Paste a long statute citation and get its compact Bluebook-style abbreviation. Free, no sign-up.
What this tool does
Statute citations in full are long: code name, title number, section symbol, section number, year. In footnotes they repeat, and every repetition costs a line. Bluebook compaction drops what the reader already knows from context — the code name after first use, the year when unchanged — under strict rules. This compactor applies those rules to a full citation you paste and returns the compact form, with a note of what was dropped and why, so the short form stays traceable.
Why it matters
Good citations do quiet work. They let a reader find every source you used, they show that your argument rests on real evidence rather than memory, and they protect you: a clean reference list is much harder to challenge than a vague one. Most marks lost on referencing are not lost on difficult sources. They are lost on small, repeated slips — a missing year, a swapped initial, a title in the wrong case — that a quick tool pass catches before submission.
How to use it
- Paste the full statute citation.
- Say whether this is a first use or a later use.
- Copy the compact form.
Worked example
Full ‘Clean Water Act, 33 U.S.C. § 1251 (2018)’ on later use compacts to ‘§ 1251’ when the code is unchanged from the previous citation. First use keeps the full form. The tool shows both, labelled, so you pick the right one for the position.
Tips for good results
Never compact across a change of code. A short ‘§ 1251’ after switching from U.S.C. to C.F.R. points at the wrong book.
Work from the source itself, not from another paper’s copy of it. And keep one style for the whole list: a single mixed entry undermines an otherwise perfect bibliography.
Honest limits
Compaction rules depend on what came before in your document — the tool cannot see your earlier footnotes, so it compacts on the assumption you state (first vs later use). Short forms that would be ambiguous across two codes are flagged rather than compacted.
Common mistakes to avoid
Common mistakes to avoid: copying a reference from another paper without checking it against the original, trusting a PDF filename for the title or year, and mixing two styles in one list. Each of these looks harmless alone and careless together. Run the tool, read its output once, and compare it with the source itself before you paste it into your document.
Before you submit
Run through this short check before you submit: is every author name spelled as it appears on the source, is every year present and correct, and does every in-text citation have a matching entry in your reference list? Read the list once from top to bottom rather than skimming it. Most referencing errors are found in that single slow read, and fixing them there is far cheaper than fixing them after a reviewer finds them. If one entry still looks odd after that read, check it against the original source before you change anything else.
Frequently asked questions
Is this tool really free?
Yes. It runs in your browser on this page, with no account and no payment. Nothing you paste leaves your computer.
Do I still need to check the result?
Yes, once. Tools apply rules; they cannot verify facts about your source. Compare the output with the source itself before submitting.
Can I use the output in my paper?
Yes. The output is a formatted reference or analysis for your own work. Keep the source’s facts accurate and the formatting consistent across your list.
What if the tool’s output differs from my style guide?
Trust the style guide. Tools encode the common rules of a style; your university or journal’s own sheet wins every disagreement. Use the tool to do the routine work, then apply the local rule where it differs.
