1897 to 1907 a commission was engaged in an effort to codify the great mass of accumulating legislation. The work of the commission involved an expenditure of over $300,000, but was never carried to completion." Only the Criminal Code of 1909 and the Judicial Code of 1911 were enacted. In the absence of a comprehensive official code, private publishers once again collected the more recent statutes into unofficial codes. The first edition of the United States Code (published as Statutes at Large Volume 44, Part 1) includes cross-reference tables between the USC and two of these unofficial codes, United States Compiled Statutes Annotated by West Publishing Co. and Federal Statutes Annotated by Edward Thompson Co. Official code During the 1920s, some members of Congress revived the codification project, resulting in the approval of the United States Code by Congress in 1926. The official version of the Code is published by the LRC (Office of the Law Revision Counsel) as a series of paper volumes. The first edition of the Code was contained in a single bound volume; today, it spans several large volumes. Normally, a new edition of the Code is issued every six years, with annual cumulative supplements identifying the changes made by Congress since the last "main edition" was published. The official code was last printed in 2018. Digital and Internet versions Both the LRC and the GPO offer electronic versions of the Code to the public. The LRC electronic version used to be as much as 18 months behind current legislation, but as of 2014 it is one of the most current versions available online. The United States Code is available from the LRC at uscode.house.gov in both HTML and XML bulk formats. The "United States Legislative Markup" (USLM) schema of the XML was designed to be consistent with the Akoma Ntoso project (from the United Nations Department of Economic and Social Affairs) XML schema, and the OASIS LegalDocML technical committee standard will be based upon Akoma Ntoso. A number of other online versions are freely available, such as Cornell's Legal Information Institute. Annotated codes Practicing lawyers who can afford them almost always use an annotated version of the Code from a private company. The two leading annotated versions are the United States Code Annotated, abbreviated as USCA, and the United States Code Service, abbreviated as USCS. The USCA is published by West (part of Thomson Reuters),
