Do you know what book holds the record of being the longest book ever written in the world? It is Yongle Dadian - "The Encyclopedia of Yongle Emperor's Reign in Ming Dynasty.” It took 4 years for 3,000 scholars to finish the compilation of 11,095 volumes and 22,877 chapters in 1408. The encyclopedia has an estimated 370 million Chinese characters.
As to much shorter but surely no less important Bluebook, check out "Introduction to Basic Legal Citation" by Peter W. Martin. It has good information on legal citation, which you may want to read if your goal is to join a law review or write for one.
If you want to streamline your legal research and writing, CiteIt! may be the right choice for you. It is a software that automatically formats legal citations according to The Bluebook or The ALWD Citation Manual, inserts properly-formatted citations into your word-processing document, creates a table of authorities and makes it easy for you to store, search and organize your legal research. You can download a free trial version.
If you must write a research paper for any course or journal that uses MLA, APA or Chicago style, Slate Citation Machine is a free simple-to-use online citation tool to reformat a citation to the style you need.
Finally, here is a good compilation of resources for writing a research paper from St. Ambrose University Library. This is how I found the Thinking Page, which offers information on improving organizational and individual thinking.
