Over the course of a month we receive many newsletters. Some of them are really quite good and they may (depending on your area of interest) be useful to you. We will try to call the good ones to your attention on a regular basis.
If you are interested in international mining news, be sure to check out Behre Dolbear's weekly newsletter (which you can subscribe to for free). The most recent newsletter, published March 23, 2009, notes that while "mining megadeals will continue to slow...niche deals will increase." This is a great resource for those interested in the mining sector.
On the other hand, a quickly growing area of specialization involves accounting and sustainability. The ACCA Accounting and Sustainability newsletter is also freely available for e-mail subscribers. The most recent issue includes coverage of sustainability, corporate social responsibility, and socially responsible investing news. ACCA, the Association for Chartered Certified Accountants, is a London-based professional accrediting and education body for accountants. ACCA also publishes high quality research on the accounting-related aspects of sustainability. As is typical with many European professional organizations, ACCA is aggressive in its efforts to tie its profession more closely into the entire environmental and sustainability movement. They see "sustainability" as an important concept and one that will increasingly open up opportunities for accountants.
Finally, if renewables is your specialty then be sure to check out FOREcast: Funding Opportunities for Renewable Energy, edited by John Herrick, former chief counsel for the U.S. Department of Energy in Golden, Co., and one of America's top experts on renewable energy project finance. The March 23, 2009 issue includes stories on "Stimulus Package Expands Upon and Improves DOE Loan Guarantees," a summary of relevant tax and energy funding opportunities in the Economic Recovery Act, and an analysis of the Obama Administration's top energy appointees. (Mr. Herrick also teaches the leading law school course in America dealing with renewable energy financing.)
