"The speech accent archive is established to uniformly exhibit a large set of speech accents from a variety of language backgrounds. Native and non-native speakers of English all read the same English paragraph and are carefully recorded. The archive is constructed as a teaching tool and as a research tool. It is meant to be used by linguists as well as other people who simply wish to listen to and compare the accents of different English speakers" (About page, ¶2, 2012.04.10).
"The Academic Word List (AWL) was developed by Averil Coxhead at the School of Linguistics and Applied Language Studies at Victoria University of Wellington, New Zealand. The list contains 570 word families which were selected because they appear with great frequency in a broad range of academic texts. The list does not include words that are in the most frequent 2000 words of English (the General Service List), thus making it specific to academic contexts. The AWL was primarily made so that it could be used by teachers as part of a programme preparing learners for tertiary level study or used by students working alone to learn the words most needed to study at colleges and universities."
This page gives a compact listing of all the word families in the AWL, divided by sublist, each word linked to a simple definition page.

"The main part of this website, the History, can be read as a kind of story, in chapters, following the development of the English language from its Indo-European origins, through Old English and Middle English to Early Modern English and Late Modern English, before a brief look at English Today. But there is also section on Language Issues (including How New Words are Created, Language and Geography and English as a Global Language), a Timeline of important dates in the development of English, a Glossary of some of the technical and historical terms used, and a list of Sources and Links."
