An Introduction to Chemistry by Mark Bishop. There are two versions of this current textbook, both containing the same information but organized differently: the 'Chemistry-first' version begins with actual 'chemistry' — that is, chemical equations and reactions. The alternative 'Atoms-first' format saves this stuff for later, and begins with atomic theory and bonding. To download PDF versions, select Chemistry-First or Atoms-First. Please note that although you may download these for free, Mark asks that those who make regular use of them pay a shareware fee of $20. Individual chapters for iPad, iPhone, Android devices and Kindle are also available: Chemistry-First, Atoms-First.

Chemical Principles, 3rd Ed (Richard Dickerson, Harry Gray and Gilbert Haight, 1979) - This 1979 text is well-regarded and still good for most first-year General Chemistry courses. Each chapter can be downloaded as a separate pdf file; to see which one you need, move your mouse over the image and the title will appear.

Chemical Principles (CK-12 foundation; Sharon Bewick, Johathan Edge, Therese Forsythe, Richard Parsons) A single 900-page, 51Mb pdf file; download.

College-level online lectures

UC-Berkeley eChem1a: Online General chemistry - These professionally-made videos, most of which feature Prof. Mark Kubinec, are of outstanding quality - perhaps the best college-level general chemistry tutorials available.. There are more than 400 of them, organized into 38 lessons; many of the latter contain problem-solving tutorials, interactive quizzes, and lab demonstrations. Most of the videos are fairly short (5-15 min) and can be accessed in any order.

MIT Principles of Chemical Science - This MIT OpenCourseWare course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. More MIT Chemistry lectures and videos.

Yale Freshman Organic Chemistry - Another excellent series, this one covers the two-semester first-year course which includes organic chemistry. These are llive classroom lectures, given by Prof. J. Michael McBride. His descriptions of the historical development of important concepts is unusually good, and adds to their understanding. Some of the projected slides are hard to read.

Web-based resources for General Chemistry

ChemWiki: The Dynamic Chemistry E-Textbook - a collaborative approach toward chemistry education where an Open Access textbook environment is constantly being written and re-written by students and faculty members resulting in a free Chemistry textbook to supplant conventional paper-based books. The material is organized into sections for analytical, biological, inorganic, organic, physical and theoretical chemistry. Each of these contains topics ordinarily included in 'general' chemistry, as well as more advanced ones that go beyond first-year college level.

General Chemistry Online! - an interactive guide and Web resource for students and teachers of introductory college chemistry, maintained by Fred Senese of Frostberg State University (MD). A well-organized wealth of material, including collections of notes and guides for introductory General Chemistry, skills checklists and online self-grading examinations, and a Q&A column.

An Introduction to Chemistry - an online version of a text by Mark Bishop of Monterey Peninsula College (CA). It is intended primarily for students in beginning chemistry courses. ($20 'donate-ware', and well worth it!)

Virtual Chembook - this nicely-done site by Charles Ophardt of Elmhurst College covers a wide swath of general, organic, and environmental chemistry. The text material is interesting and well written without attempting to be encyclopedic.

General Chemistry Virtual Textbook - a free collection of comprehensive, in-depth treatments of various topics, intended to supplement or replace conventional textbook treatments. It is aimed mainly at the first-year college level, but advanced high school students will find much of it useful. (Steve Lower, Simon Fraser University)

The Chemogenesis Webbook - this extensive, excellent and comprehensive site by Mark Leach tells how chemistry emerges from the Periodic Table and bifurcates into the rich and extraordinary science that we know and experience.

Chemistry tutorial series on YouTube and other video collections - a summary of the major collections, including the Khan Academy, and those done by various teachers, mostly at the high school level.

WikiBooks on Chemistry - Many topics in general chemistry are covered here, and are worth looking at. But as in any 'wiki-' type project to which anyone can contribute, the quality is variable, and the visual design is primitive.

Tanner's General Chemistry - a large collection of pages on matter (including quantum theory), physical chmistry, electrochemistry, and aqueous solutions.

AUS-e-TUTE -an Australian 'science education site being developed by experienced teachers.' They offer tutorials, texts, games, drills to registered members, as well as an extensive collection of tutorials for non-members.

Chemistry Web Resources - this site maintained by Ron Rinehart of Monterey Peninsula College contains a wealth of material oriented toward chemical education, all well organized in a visually-attractive way.

ChemPaths: Student Resources for General Chemistry - a comprehensive collection of tutorials from the Chemical Education Digital Library

KnowledgeDoor - an excellent compendium of Chemistry- and Science-related data, in many ways more comprehensive than the Handbook of Chemistry and Physics, and certainly more convenient to use. Should be bookmarked by every serious Chemistry student!

The ChemCollective student page has links to practice problems and tutorials on various topics.

College physics for students of biology and chemistry - This hypertextbook by Ken Koehler is nicely organized and is the ideal place to go when your Chemistry textbook lets you down.

How to pass chemistry - sound advice that is widely ignored.

{High School Resources on the Web} - this extensive collection of links at Bob Jacob's Wilton HS site apparently disappeared in early 2008, but this link to a 2007 archived version should still be useful for both high school and college-level General Chemistry.

This Week in the History of Chemistry - part of Carmen Giunta's (Le Moyne College) excellent Classic Chemistry site, 'This Week' presents mini-timlines covering the current two-week period.

{Discovery and naming of the chemical elements} - this site by David Trapp organizes the elements according to whether their names are derived from celestial objects, places, minerals, etc.

Discovery of the elements - {Elementistory} provides very brief summaries; the {Los
