Congratulations! We wish you the best in your future work. Part of that success will rest on continuing to be informed and educated about the world around you. As you've learned by now, library web pages offer access to all sorts of useful online dictionaries, encyclopedias and article database sites.
Unfortunately, because of licensing arrangements, we can't continue to offer our students access to these resources from off campus after they finish school. (The cost would be far more than we can support.)
However, you do have access to similar resources through the efforts of the NY State Library. If you go to this site, and click on the part of the state you live in, you can put in your library card or driver's license # and access a number of useful online resources, much like those you have used here.
