noodle tools' noodlebib is a paid service, but there is a free version online called noodlebib express. i have no experience with the paid version because i find noodlebib express to do everything i require. this tool can save students time and confusion. it is a tool i use as an adult for graduate school, too.
final verdict
noodle tools does exactly what it is supposed to do. it creates citations in various formatting styles based on information entered by the user through an online form. noodlebib is far more useful than noodlequest. in previous posts, i expressed my displeasure with specialized search engines. i equated them to training wheels. there is only one option when in need of a search engine, google. google also has google scholar, which specifically seeks scholarly works from thousands of publications. i use noodle tools for citation help, not for performing actual research.
