First and foremost I must thank my fellow-linguists at the Yahoo! Group Artificial Languages for all the help they've given me over the years. I've been a member of this group for over two years now, I was the second member, and I joined three days after it was founded. Now our leader, Drake, has offered me and another one of the diehard conlangers William the role of co-founder. :) I really wouldn't have been able to create the language without the help these people have given me.

Adelic What can I say? I love this language. It's one of the first I ever came across.

An Introduction to Old Norse This I've used to get a sense of Skaldic meter and verse for the my Cepperjoleddicg poetry and for its helpful glossary in the back. Of course, the primary focus of the book is the sagas, which I've taken great pleasure in reading. There is also an excellent introduction which explains the origins and interactions of the different Germanic peoples.

Beowulf: A New Verse Translation (Seamus Heaney's translation) This gave me a good sense of how the ancient Germanic people wrote poetically.

Brendan's Language Page This is a phonetic guide to some fifty-odd languages. I used it to decide how to fill out Cepperjoleddicg's phonetic inventory.

Chamber's Etymological English Dictionary Where would Cepperjoleddicg be without Chamber's? Nowhere close to where it is today, that's for sure. Now, I have come across etymological dictionaries that are more complete, but I keep on using Chamber's because it's so usable. Very user-friendly. And plus, at this point, it's like an old friend. The spine's broken, the pages are worn and covered with my fingerprints, and the inside cover bears grass stains from the time I let Eric borrow it and he dropped off the Carter's back porch.

Essentials of Early English Incredibly helpful. This book contains three grammars: one of Old English, one of Middle English, and one of Modern English; selected Old English texts; and an Old English glossary.

MacBain's Etymological Dictionary of Scottish Gaelic I bought this in hardcopy about a year ago only to discover that night that there was a hypertext version available. Alas. I highly recommend MacBain's for anyone interested in Gaelic or Gaeldom.

Modern English to Old English Vocabulary This was my first Cepperjoleddicg-specific resource. I was lucky to find something so complete so early on.

Obsidian's Lair You find help in interesting places, sometimes. A guide to different peoples' pantheons. I used the Germanic one to form some words and to name the months and the days of the week.

Scallin and Kakarak Kakarak's not really my thing, but Scallin reminds me in a lot of ways of Cepperjoleddicg.

Russian (Teach Yourself Books) A nifty little book. (I would have ordered it a bit differently, but hey, when I write my books I can do them however I like, I guess.) Germanic and Slavic langauges are closely related, and this guide to Russian grammar helped me decide how to handle some of the finer, more esoteric points in Cepperjoleddicg (especially Rauþøþlį dialect) style.

Swedish (Teach Yourself) Handy.

The Celtic Consciousness This book is mainly about Celtic culture and history, but it has a few chapters on language that have really helped me to decide how to handle my analytic constructions.

They Have a Word For It: A Lighthearted Lexicon of Untranslatable Words & Phrases This book has helped contribute to some words that I feel have given the language a very special, Germanic feel.

Verbix.com This is a great online verb conjugator that's constantly expanding! I used it to decide which verbs would be strong and which would be weak.

Welsh Dictionary This page is a fossil but it's the best you can find. I guarantee it.

yourDictionary.com I've known about this page as long as I've known about the internet and I've used it for ages. It provides grammars, dictionaries, thesauri, etymologies, word games, and other language tools in thousands of languages (including a few in invented languages.)
