Biodiversity Heritage Library - BHL

Inspiring discovery through free access to biodiversity knowledge.

The Biodiversity Heritage Library improves research methodology by collaboratively making biodiversity literature openly available to the world as part of a global biodiversity community.

BHL also serves as the foundational literature component of the Encyclopedia of Life.

Die "Biodiversity Heritage Library" ist ein Projekt zur Digitalisierung von Literatur zum Thema Artenvielfalt/Biodiversität. Sie wurde um 2005 ins Leben gerufen und beschränkte sich zunächst auf zehn (ab 2009 zwölf) US-amerikanische und britische Bibliotheken.

Nach "Gallica" und "AnimalBase" war "BHL" damit das weltweit dritte große und nischenübergreifende Digitalisierungsprojekt. 2006 wurde damit begonnen, die digitalisierte Literatur massenweise ins Netz zu stellen. 2008 wurde die Bedeutung von "Gallica" und "AnimalBase" überrundet. Heute ist BHL das weltweit mit weitem Abstand führende Digitalisierungsprojekt für Biodiversitätsliteratur.

Im April 2009 waren 13 Millionen Seiten und 11.000 Werke digitalisiert, Mitte September 2014 lag die Zahl der digitalisierten Bücher bei ca. 86.700 Titeln, ca. 150.000 Bänden bzw. ca. 44.655.000 Seiten (Quelle: BHL-Portal). Dadurch, dass die Bibliotheken nur copyright-freie Bücher digitalisieren dürfen, konzentrierte sich die Digitalisierung bei BHL bislang hauptsächlich auf Literatur von vor 1920. Einige Bibliotheken setzen die Grenze bei 1899. Dies hatte schon nach wenigen Jahren den Effekt, dass es in der Zoologie und Botanik inzwischen so ist, dass der Zugang zu Fachliteratur von vor 1900 wesentlich leichter ist als zu der, die zwischen 1920 und 1990 erschienen ist.

Conservation (W3)

The Conservation Alliance is a non-profit organization of outdoor businesses whose collective annual membership dues support grassroots citizen-action groups and their efforts to protect wild and natural areas.

Founded in 1990, "Raincoast Conservation Society" is a non-profit research and public education organization. We work in partnership with scientists, First Nations, local communities and Non-governmental Organizations to build support for decisions that protect marine and rainforest habitat on BC’s central and north coast.

Most Endangered Parks
This year the National Parks Conservation Association listed the following parks as the most endangered parks. I included the main reasons and they are linked to the National Park Service sites.

• "Big Thicket National Preserve" - a timber company is selling land that surrounds the park. If the new buyer decided to clear cut the land it could have adverse effect on the Big Thicket National Preserve.
• "Denali National Park and Preserve" - allowing motorized access into certain parts of the park that are closed to motorized access. This could affect the wildlife. Also potentially building a $200 million dollar road on the North side of the park could affect the caribou herds and wolves.
• "Everglades National Park" - which is one of the worlds largest fresh water marshes faces many problems including pollution, low water levels, and poor enforcement of regulations.
• "Glacier National Park" - our spectacular park in Montana along the Canadian border is facing threats from mining, more highways along the southern border, and potential pollution from oil and gas companies sites right outside the park.
• "Great Smoky Mountains National Park" - air pollution is a major problem here. This park has lots of acid rain, haze, and ozone. Not the kind of "Smoky" that we need in this park. Please tell the Tennessee Valley Authority to clean up it's power plants like it promised and then didn't.
• "Joshua Tree National Park" - development and a potential large land fill that is bordered by the park. This could cause air pollution, noise and light pollution.
• "Ocmulgee National Monument" - this national monument , near Macon, Georgia, has evidence of 12,000 years of human habitation in and around this site. Chronic underfunding and development around the site puts priceless artifacts at risk.
• "Shenandoah National Park" - air pollution has cut the views from the parkway from 100 miles to as little as one mile on some summer days. Also acid rain affects the trees and wildlife such as brook trout. Coal and oil burning power plants need to update their pollution control equipment.
• "Virgin Islands National Park" - potential development near the park could cause damage to coral reefs, mangrove shorelines and critical bird habitat. Also Government regulations need to be enforced including a no-take zone (no fishing zone) in and around the Virgin Islands Coral Reef National Monument.
• "Yellowstone National Park" - pollution due to snowmobiles in the winter (which have caused some park rangers use hearing protection and wear respirators while working around all the pollution and noise caused by the snowmobiles). Also there is a risk of potential large coal fired power plant near Yellowstone which could cause air pollution.

The National Parks Conservation Association was founded in 1919 to protect our National Parks.

Nature's mission statement

Nature's original mission statement was published for the first time on 11 November 1869. The journal's original mission statement was revised in 2000. The original mission statement is reproduced below:

THE object which it is proposed to attain by this periodical may be broadly stated as follows. It is intended

• FIRST, to place before the general public the grand results of Scientific Work and Scientific Discovery ; and to urge the claims of Science to a more general recognition in Education and in Daily Life ;
• And, SECONDLY, to aid Scientific men themselves, by giving early information of all advances made in any branch of Natural knowledge throughout the world, and by affording them an opportunity of discussing the various Scientific questions which arise from time to time.

To accomplish this twofold object, the following plan will be followed as closely as possible :

Those portions of the Paper more especially devoted to the discussion of matters interesting to the public at large will contain:

• I. Articles written by men eminent in Science on subjects connected with the various points of contact of Natural knowledge with practical affairs, the public health, and material progress ; and on the advancement of Science, and its educational and civilizing functions.
• II. Full accounts, illustrated when necessary, of Scientific Discoveries of general interest.
• III. Records of all efforts made for the encouragement of Natural knowledge in our Colleges and Schools, and notices of aids to Science-teaching.
• IV. Full Reviews of Scientific Works, especially directed to the exact Scientific ground gone over, and the contributions to knowledge, whether in the shape of new facts, maps, illustrations, tables, and the like, which they may contain.

In those portions of "NATURE" more especially interesting to Scientific men will be given :

• V. Abstracts of important Papers communicated to the British, American, and Continental Scientific societies and periodicals/
• VI.Reports of the Meetings of Scientific bodies at home and abroad.

In addition to the above, there will be columns devoted to Correspondence.

The "Partnership for the National Trails System" ("PNTS") was established in 1995 to facilitate interaction and cooperation among the various private groups and goverment agencies involved with the national scenic and historic trails of the National Trails System.

The National Trails System is the network of scenic, historic, and recreation trails created by the National Trails System Act of 1968.

These trails provide for outdoor recreation needs, promote the enjoyment, appreciation, and preservation of open-air, outdoor areas and historic resources, and encourage public access and involvement.
