Here's a search engine which allows you to submit a query to a variety
of different reference collections - all from a single page. For example,
you can search dictionaries, thesauri, translators, library tools, geographical
tools, financial tools, shipping and mailing tools, and more.
Here's a very inclusive collection from Purdue University. Resources
range from writing tools such as dictionaries (of several different
languages), periodic tables, and maps and travel directories.
This CLN Theme Page has links to information about English Grammar
and Style. Students and teachers will find curricular resources (information,
content...) and reference materials (e.g., style books) to help them
learn about this topic. In addition, there are also links to instructional
materials (lesson plans) which will help teachers provide instruction
in this theme.
Searches can be done in either language. With appropriate software,
you can hear the word pronounced. Search results include related words
and the opportunity to explore further.
