When starting your research in chemistry and associated topics, you have to clarify your topic, narrow it down and decide what kinds of sources you will need. These may include print books and journals, eBooks and eJournals, databases and websites.
In the sciences you may also need studies, particularly empirical ones; and, in almost every discipline you will have to use scholarly or peer-reviewed journals. Some databases (such as EBSCOhost) allow you to narrow your search to these types of formats.
EBSCO and ProQuest databases and WorldCat provide citation help. When using these features, it is still a good idea to check the citations provided against the Style manual being used. Check the Citation Help tab above for more information.
Many of your professors may want you to differentiate between sources, primary, secondary or tertiary. There is also a differentiation between research and review article.
The ChemWiki project is a collaborative approach toward chemistry education where an Open Access textbook environment is constantly being written and re-written partly by students and partly by faculty members resulting in a free Chemistry textbook to supplement conventional paper-based books. Success of the project will be gauged by the number of students who consult the ChemWiki and the number of Chemistry courses that eventually adopt the ChemWiki as the sole textbook for class needs. Anyone can view, although a freely available account is required to edit the site modules.
