Following is the list of entries in John Lindow's Handbook of Norse mythology. Most of those should be Wikipedia articles or redirects to Wikipedia articles. Sometimes I've broken up an entry into more than one link.
I think this is a good book to use because it is not a specialist work like Rudolf Simek's Dictionary of Northern Mythology. Rather it is a part of a "Handbook of X mythology" series and written for relative laypeople.
Initially 146 red links by my hand count. Most are easy redirects. I'm working my way down.
- Ægir's Daughters - Referred to in Ægir but deserves its own article.
- Æsir-Vanir War - Referred to elsewhere but deserves its own article.
- Álfablót - Has a decent section in blót but may deserve its own article.
- Almáttki áss - A genuine omission.
- Andlang - A difficult case.
- Aurboda - A genuine omission.
- Barri - A genuine omission, if not a serious one.
- Beli - There's a problem here. Beli the giant doesn't have a page.
- Bergbúa tháttr - A genuine omission.
- Bil and Hjúki - Hmm... I'll have to check this better.
- Billing's Girl - I'll have to check this again.
- Bláin - Redirecting to Ymir.
- Bound Monster - Ignore for now.
- Bous - Should maybe redirect to Váli (son of Odin)
- Brimir - Redirecting to Ymir
- Dáin - Okay, I guess. Very little, but then there's not much to say.
- Dísablót - A genuine omission, it seems.
- Dísir - This seems to be a mess, need to look into it.
- Eggthér - A genuine, if not serious, omission.
- Egil - Something of a mess, but so is Lindow's entry.
- Eikinskjaldi - A genuine, if somewhat trivial, omission.
- Eldir - A genuine trivial omission.
- Falhófnir - A genuine but small omission.
- Fimbul- - A genuine omission, though Wikipedia isn't a dictionary. I'm of two minds here.
- Fjölvar - A genuine omission, I suppose.
- Fjörgyn - Redirects to Jord, which is okay, I suppose.
- Game of the Gods
- Gefn - Thorny. Need to check.
- Gísl - Should be checked.
- Gjallarbrú - Seems to be a genuine omission.
