It's arranged in order of the Bluebook rules (10-14) for different types of primary authorities: Cases, Constitutions, Statutes (both codified and session law), Legislative Materials, Administrative & Executive Materials.
Copy/paste up to 100 citations into Lexis's Get & Print or Westlaw's Find & Print tool.
First try searching International Cases on Westlaw and Lexis's Cases collection in the International tab (these collections are limited, and are NOT searched when a citation search is launched from the home page of these services). Citation formatting is not well standardized, so try searching by case name or other details as well.
Many jurisdictions' case sources may be available only in print; search for court reporters in print using LawCat (the Law Library's catalog) (search by the publication/reporter name, which is probably abbreviated in the citation, not by the case name or other details):
United States Code on HeinOnline - go to volume 1 of the most recent edition (the edition date is often 5-6 years out of date), and consult the Contents page (usually around page V of volume 1); under "Organic Laws of the United States" find the page for the Constitution (e.g., vol. 1, page LXI in the 2018 edition). Unless there has been a constitutional amendment since the date of the most recent edition, you will not have to check the Supplement. Download PDFs of just the page(s) with the cited portion, as no publication-specific information is needed for citation formatting.
State Constitutions on Hein Online - variously-sourced versions of current and historical versions of U.S. state constitutions. Download PDFs of just the page(s) with the cited portion, as no publication-specific information is needed for citation formatting, but note which version from Hein Online.
Constitutions of the World Illustrated on Hein Online provides full text of many constitutions and analogous fundamental laws, current and historical.
If an electronic version is acceptable, copy/paste up to 100 citations (do not include date) into Lexis's Get & Print or Westlaw's Find & Print tool.
If you require page image copies, these are available at the Law Library only for federal and California statutes
In rare cases, an author may cite to a codified provision as it existed at a particular date, rather than to the current code. If in doubt, confirm with the lead editor that the historical version should be collected.
These citations may be difficult to decipher, and sources are often difficult to track down -
These are often hard to track down, or even recognize as such based on the citation information. Don't despair! Consult a Reference Librarian.
