Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.

Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Federal statutes and regulations follow a similar publication paradigm: they are published first in chronological order and, then, are later codified by subject. The uses of various publications and web sites that describe the regulations promulgated by Federal agencies and the statutes passed by the U.S. Congress are examined here.
A typical statute may establish an obligation or a mandate on behalf of a Federal agency. In order to comply with that mandate, the agency will promulgate a regulation as to how the agency will enforce compliance with the statutory requirements. This is a simplified version of the relationship between statutes and regulations.
Finding Public Laws and Federal Statutes
To understand how to locate specific statutes by subject or different forms of citation it is necessary to recognize how a statute is created. The U.S. Congress meets in a two-year term which consist of two annual sessions, which is termed as a Congress. During each Congress, the U.S. Senate and House of Representatives consider over 5000 bills and enact several hundred statutes in the form of acts and joint resolutions. The statutes can range from simple designations of commemorative days to complex legislation regarding environmental, economic and social issues, which will span hundreds of pages of text.
Each law passed is designated as either a public law or a private law, and is assigned a number indicating the chronological order in which it is passed. Public laws are designed to affect the general public while private laws are passed to meet the special needs of an individual or group. Only public laws become part of the statutory code, the U.S. Code. Both will appear in separate series in the session laws, the U.S. Statutes at Large.
HeinOnline's U.S. Statutes at Large Library provides searchable, online access to Public Laws, Private Laws, Presidential Proclamations, and Treaties published in the U.S. Statutes at Large from its inception in 1789 to 2011.
As bound volume sources of session laws, The Library maintains the U.S. Statutes at Large (K42 .A3), which are published by the Government Publishing Office and the West publication that features selective legislative history documents, which is entitled the United States Code and Congressional Administrative News (K35 .U5).
The Interior Library also provides access to session laws within the paperback advance sheets of two commercial publications: the United States Code and Congressional Administrative News (K35 .U5) and the U.S. Code Annotated (KF 62 .W45). Session laws in the form of slip laws constitute the official text of a statute; they are housed in the Library near the U.S. Statutes at Large.
The public and private law numbers run in sequence, starting anew at the beginning of each Congress. Since 1957, the public laws have been prefixed for easier identification by the number of the Congress. For example, the first Public Law of the 106th Congress is designated Public Law (or PL) 106-1. Prior to 1957, public and private laws had citations as chapters and as a Statute at Large.
A typical statute cite will read, for example, (both before and after the 1957 change in numbering public laws) as 99 Stat. 713, which meant that it could be located in volume 99 of the U.S. Statutes at Large at page 713.
Tables that correlate Public Law and U.S. Statutes at Large cites are published in the Table volumes of the U.S. Code Annotated and at the end of each volume that completes a legislative session of the United States Code and Congressional Administrative News (K35 .U5). These tables will also provide access to specific citations to the codifications embodied in the U.S. Code and the U.S. Code Annotated.
The U.S. Code, the U.S. Code Annotated, the United States Code and Congressional Administrative News, and the U.S. Statutes at Large contain subject indices and Popular Name Tables to facilitate the location of specific statutes. The U.S. Code Annotated has several features that appear with each statute which none of the other statutory search tools contain. These include:
annotations in the form of summaries of holdings of cases that have construed the statute
annotations in the form of notes on the history of and amendments to the statute
annotations to relevant practice sets, legal periodicals and treatises
cross-references to similar and related statutes
To summarize, the following chart illustrates what each tool contains relevant to the act with the popular name "Forest Resources and Conservation and Shortages Relief Act of 1990" and the different citations used as a reference point in each set.

Public Laws 93rd Congress (1974) to the present, through Congress.gov
In its simplest form, the system of publishing Federal agency regulations is based on a daily publication entitled the Federal Register, which constitutes a counterpart to the session laws, and a codification of promulgated regulations entitled the Code of Federal Regulations (CFR). Each of these publications contain other components as detailed below.
The location of Federal agency regulations in these official publications involves the use of a variety of Federally and commercially produced indices publications as described below. The Internet provides opportunities to search specific annual sequences of both publications at the following web sites:
The Federal Register has been published daily, Monday through Friday since March 14, 1936, pursuant to the Federal Register Act, 49 Stat. 500, 44 U.S.C. 301 et seq. The Federal Register publishes the following types of documents:
Presidential documents - these include Proclamations and Executive Orders
Rules and regulations - these are published with a summary, effective dates, contact persons, and relevant supplementary information
Proposed rules - documents which notify the public of proposed regulations and solicits comments within a specific time frame
Notices - notices of hearings and investigations, committee meetings, agency decisions and rulings, delegation of authority, filing of petitions and applications, and statements from agencies regarding organization and functions
Each daily issue of the Federal Register contains the following "Reader Aids":
Customer Service telephone numbers
Web site addresses
E-mail addresses for PENS (Public Law Electronic Notification Service) and Federal Register reference questions
Table of Federal Register pages published for each specific date in the current month
List of CFR parts affected/changed during the current month - this cumulative list provides the user with appropriate Federal Register cite to locate specific CFR changes
Reminders - these include reminders of specific rules going into effect on that day (and on the next day also in Friday's issue), comments due next week and a list of public laws passed this week
Each Monday, the Federal Register contains a CFR checklist, which describes the order of CFR titles, stock numbers, and the prices and revision dates for each issue published; this list provides an inventory of what a current set of CFR should contain.
The CFR is divided into 50 titles. Each title is updated once per calendar year on the following schedule:
Titles 1 through 16; January 1
Titles 17 through 27; April 1
Titles 28 through 41; July 1
Titles 42 through 50; October 1
The revision dates are printed on the cover and title pages of each issue. The revision dates on each CFR issue is crucial to the updating of each section therein. That date allows users to rely upon the List of Sections Affected to locate updates and proposed changes to regulations as published in the Federal Register. The List of Sections Affected is also available on the Internet.
The Library maintains a variety of subject indices to support research in the Federal Register and the Code of Federal Regulations. These include:
CFR Index - official GPO publication, maintained since 1970
List of Sections Affected - official GPO publication, maintained since 1949
Federal Register Index - official GPO publication, 1936-82
CIS Federal Register Index - 1984-98
A tutorial on the uses of the Federal Register is available on the Internet and is in the Library collection as The Federal Register: What It Is and How to Use It (KF70 .A2U58 1992). Detailed procedures for the submission of proposed rules, comments and rules to the Federal Register are available in the Federal Register Document Drafting Handbook (KF70 .A21 1997).
