Welcome to the Stanford Encyclopedia of Philosophy (SEP), which as of March 2018, has nearly 1600 entries online. From its inception, the SEP was designed so that each entry is maintained and kept up-to-date by an expert or group of experts in the field. All entries and substantive updates are refereed by the members of a distinguished Editorial Board before they are made public. Consequently, our dynamic reference work maintains academic standards while evolving and adapting in response to new research. You can cite fixed editions that are created on a quarterly basis and stored in our Archives (every entry contains a link to its complete archival history, identifying the fixed edition the reader should cite). The Table of Contents lists entries that are published or assigned. The Projected Table of Contents also lists entries which are currently unassigned but nevertheless projected.

İnsanlıkla yaşıt bir bilim dalı olan biyografi, toplumların sosyal ve kültürel gelişmişliğinin de önemli göstergelerinden biridir. Bu anlamda dünyanın en zengin biyografi geleneği, İslam medeniyetine ve dolayısıyla onun önemli bir parçası olan Türk toplumuna aittir.

Türk Edebiyatı İsimler Sözlüğü başlangıçtan günümüze kadar Türk edebiyatına ait şair ve yazarların biyografilerini modern biyografi anlayışına göre ele alan bir çalışmadır. Genel Ağ ortamında bütün dünyanın hizmetine sunulan Türk Edebiyatı İsimler Sözlüğü, belirli aralıklarla yeni araştırmalar ışığında güncellenecektir.

Türkiye Arkeolojik Yerleşmeleri (TAY) Projesi, dünya kültür emanetlerinin önemli bir parçası olan Türkiye kültür varlıklarının bulgularının, kronolojik bir envanterinin çıkartılması ve bu bilginin uluslararası platformda paylaşılması amacına yönelik olarak tasarlanmıştır. En azından 400.000 yıl eskiye uzanan kültürel verileri barındıran Anadolu ve Trakya toprakları üzerinde, 1800'lerin ilk yarısından başlayan araştırmaların sonuçları ile çağdaş yüzey araştırmaları ve kazıların bilgileri dağınık ve çoğunlukla ulaşılamaz durumdadır. Birçok yerleşmenin yeri bilinmemekte, birçoğu da tahribatın/yapılaşmanın kurbanı olmuş ya da olmaktadır. Bu tahribata karşı ve bu emanetleri korumaya yönelik öncelikle yapılabilecek en önemli çalışma, kültürel verilerin merkezi bir yapı içinde toplanması ve derlenmesidir: Belgeleme olmadan koruma olmaz. İlk kez bu projeyle, Türkiye arkeolojik yerleşmeleri, höyükler, tümülüsler, anıtlar, mezarlıklar, ören yerleri, yerleşme yerleşme, höyük höyük, tümülüs tümülüs belgelenmektedir.

The United States Patent and Trademark Office (USPTO) is the federal agency for granting U.S. patents and registering trademarks. In doing this, the USPTO fulfills the mandate of Article I, Section 8, Clause 8, of the Constitution that the legislative branch "promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." The USPTO registers trademarks based on the commerce clause of the Constitution (Article I, Section 8, Clause 3). Under this system of protection, American industry has flourished. New products have been invented, new uses for old ones discovered, and employment opportunities created for millions of Americans. The strength and vitality of the U.S. economy depends directly on effective mechanisms that protect new ideas and investments in innovation and creativity. The continued demand for patents and trademarks underscores the ingenuity of American inventors and entrepreneurs. The USPTO is at the cutting edge of the nation's technological progress and achievement.

Built and developed by researchers, to ensure that everyone can join in Open Science. The OpenAIRE project, in the vanguard of the open access and open data movements in Europe was commissioned by the EC to support their nascent Open Data policy by providing a catch-all repository for EC funded research. CERN, an OpenAIRE partner and pioneer in open source, open access and open data, provided this capability and Zenodo was launched in May 2013. In support of its research programme CERN has developed tools for Big Data management and extended Digital Library capabilities for Open Data. Through Zenodo these Big Science tools could be effectively shared with the long­-tail of research.
