Jay Jordan and Eva Cassini

At the time Jordan joined OCLC, the nonprofit organization represented 30,000 libraries. 14 years later technological developments had completely changed the information society and the use of libraries. During Jordan’s term as president, OCLC tried to adapt to these new developments. WorldCat holdings grew during this period (to 290 million bibliographic records from 72,000 libraries) and WorldCat. org was made available on the open web. At the same time OCLC developed new services (like Question Point). OCLC made several acquisitions such as the Research Libraries Group (2006), PICA (2007), Ezproxy (2008) and OAIster (2009). OCLC sold NetLibrary in 2010. VIAF was implemented and hosted by OCLC. VIAF is a service to link identical records from different data sets together, thereby making it easier for patrons to find e. g. books from Dostoyevsky/Dosto├»evski



The precise chemical composition of these very alien lakes and seas remained unknown until 2014, when Cassini's radar instrument detected Ligeia Mare, now known to be Titan's second-largest hydrocarbon-filled lake. Ligeia Mare is brimming with an abundance of sloshing methane, and this enormous liquid reservoir is approximately the same size as two of Earth's Great Lakes combined--Lake Michigan and Lake Huron. Many planetary scientists think that the seabed of Ligeia Mare may be blanketed with a thick layer of sludge that is composed of organic-rich compounds. The scientists also ruled out the possibility that the mysterious features actually exist on Titan's surface in the form of frozen methane rain or icy lava erupted from cryovolcanoes. Such surface features would show a different chemical signature and would be visible for much longer periods of time than the bright features observed in this study. The bright features were visible from time spans of only 11 hours to five weeks. Full moons on different days. Where you live on earth rarely makes a difference as to whether the moon is full, quarter or new. This is because it takes the moon almost a month to travel around the earth and it only takes a day for the earth to turn around once. So in comparison, the moon sort of sits in the sky and waits for us to see what phase it is in. Still, there are times when the moon will be full on different calendar days in different areas of the earth.
