Turn case details into a clean Bluebook-style citation: party names, volume, reporter, page and year. Free, no sign-up.
What this tool does
Legal citations look cryptic until you see the pattern: case name, volume number, reporter abbreviation, first page, court and year. Bluebook adds italics for the case name and strict abbreviations for courts and reporters. This parser takes the pieces in plain words and returns a citation shaped the Bluebook way, plus a plain-English reading of each part so a first-year law student can check their own work instead of guessing.
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
- Type the case name, e.g. Brown v. Board of Education.
- Add volume, reporter abbreviation, first page, court and year.
- Copy the formatted citation and check the plain reading.
Worked example
Brown v. Board of Education, 347 U.S. 483 (1954): case name Brown v. Board of Education, volume 347, reporter U.S. (United States Reports), first page 483, decided 1954. The tool produces exactly that string from the five fields.
Tips for good results
Use ‘v.’ between party names, never ‘vs.’ Bluebook style always uses the single letter with periods.
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
This is a rule-based formatter for standard US case citations. It is not a legal database, it does not verify that a case exists, and it does not cover every Bluebook rule (signals, short forms, statutes and secondary sources have their own tools here). For court filings, verify against the current Bluebook.
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.
