If you're looking for a good license to make you famous and loved by the community, check out the FreeBSB license.
The LGPL (Lesser) would be good for this though the FreeBSD license is more clear and to the point. LGPL is also bad because it requires a modified version of the library to be covered under the same license.
The FreeBSB protects your copyright on redistribution of the source code, but allows developers to modify and use the library as part of a commercial project without licensing hassles. They would only need to provide a credit or footnote in an about dialog.
