VIRTUAL TEXTBOOK OF ORGANIC CHEMISTRY

Virtual Textbook of Organic Chemistry  
www2.chemistry.msu.edu/faculty/reusch/VirtTxtJml/intro1.htm
William H. Reusch, emeritus professor at Michigan State University, published his Introduction to Organic Chemistry in 1977. Readers may purchase it for a list price of $137.74; or they may access the Virtual Textbook of Organic Chemistry, which contains nearly the same information online, for free, on this surprisingly comprehensive website. Here readers will find a fully operational organic chemistry textbook, divided into the two overarching topics of General Principles and Functional Group Reactions. Within General Principles, readers will learn the basics of Structure & Bonding, Intermolecular Forces, Chemical Reactivity, Aromaticity, and other subjects. Functional Group Reactions covers Alkanes, Alkenes, Alkynes, Alcohols, and many other subjects. For readers looking for a comprehensive, freely available organic chemistry textbook, this site will be a true boon. [CNH]”

Poisonous Plants Database

URL:www.ansci.cornell.edu/plants

The people in the College of Agriculture and Life Sciences at Cornell University want to make sure that you don’t accidentally poison your livestock or pets with toxic plants. Their Poisonous Plants database includes a sizable number of entries such as oak trees (the acorns and young leaves are poisonous to horses and cattle), Daphne (toxic to cats, dogs, and humans), and rhubarb (the leaves are toxic to goats, swine, horses, and even people—who knew?). Each entry is accompanied by images of the plants, as well as answers to questions that the authors have either encountered in the past or anticipate that readers may have. The database is simple to browse—either by scientific name or common name—or users can search the database by scientific name, common name, primary poisons, or species most often affected.

Life on Earth, 4.1billion years old?

Life on Earth likely started 4.1 billion years ago, much earlier than scientists thought

Posted: 19 Oct 2015 12:41 PM PDT

“Geochemists have found probable evidence for life on Earth at least 4.1 billion years ago — 300 million years earlier than previously documented, pushing the origin of life close to when the planet formed, 4.54 billion years ago.

ProQuest Scholarly Content Now Discoverable in Google Scholar

By Africa S. Hands

From No Shelf Required:

ProQuest has marked another milestone in ease of access to its rich research content. The full text of its scholarly content – including journals and working papers – is now indexed in Google Scholar, enabling Google Scholar users to seamlessly discover and access their library’s ProQuest collections. Efficiency and productivity for both ProQuest and Google Scholar users is improved, while libraries benefit from increased usage for their subscribed collections.
