I have tried be selective in the links given here, limiting them to those that seem genuinely useful. A search with a general search engine will provide plenty more, as will some of the links provided by pages listed here. If you have any suggestions for links to sites or pages you have found particularly helpful, please send them to me. Links change and fade with surprising speed and if any of the links here no longer works, let me know.
The National Library of Ireland—Leabharlann Náisiúnta na hÉireann now offers on-line access to it's excellent exhibition on Yeats — it requires Flash and Broadband but is very full and will repay plenty of browsing.
Beyond that, of particular interest is the catalogue of Yeats’s Occult Papers as Acrobat pdf, compiled by Peter Kenny, and including the Automatic Script, which is cross-referenced to Yeats’s 'Vision' Papers.
NEW The National Library of Ireland has mounted an excellent exhibition about Yeats, in all his aspects, and has included a fair portion on Yeats's esoteric interests including A Vision. It opened on 25 May 2006 and is due to run for three years. (I am biased because I have been involved with it, but it genuinely is very good.)
The Princess Grace Irish Library, EIRData (Electronic Irish Records Dataset) used to be very useful. Although not particularly user-friendly in terms of presentation, it was compact and full. It is currently (2006) closed for maintenance (and has been for more than a year now), and will require users to register when it reopens. They tell you that you will be able to register when the database is available.
Warren Wedin’s Seminar Resources for his course at California State University, Northridge; his own listing of critical material, divided into books, journal articles, and articles in books is particularly good, last updated in 2002.
The Yeats Society of New York’s page of Web Resources is particularly comprehensive.
The Open Directory Project, "dmoz", itself a set of further links.
The Yeats Society Sligo, including information on the Yeats International Summer Schools.
The Australian Yeats Society’s Beyond Ben Bulben page.
Frank L. Ludwig’s photographs of Yeats country gives pictures of the Sligo countryside evoked in the poetry, such as Ben Bulben, Knocknarea and the Hawk’s Well. The full visual index is slow to load but offers a beautiful survey in itself.
The best chronology is John Kelly’s A W. B. Yeats Chronology. This single volume is based upon the chronologies at the beginnings of the separate volumes of the Collected Letters (general editor, John Kelly), where detailed entries appear for the years covered by the volume in question, and a broader outline for the rest of Yeats’s life. The chronology given on this site (in the Overview) is mainly drawn from this.
A chronology of Yeats's life, a clearer outline perhaps, compiled by Sam McCready.
When dealing with texts, there are many problems with web editions. The very best are excellent and have the added advantage of being searchable, but are still not as easily or reliably referred to as a printed book. If you refer to a site and the page has gone, for whatever reason, it does not have quite the same currency as even the most out-of-print book. Unfortunately few on-line texts are excellent. Many are good, having been put up by projects such as Project Gutenberg, which has standards of proof-reading, and the same goes for many other sites, including those of public-minded enthusiasts. There is still the problem that there is usually no indication of editorial principles, the actual provenance of the text or copy-text and what variants might be involved. They provide a great service and are very useful in providing a reading text, but not a substitute for the book at a scholarly level. It is not always easy to distinguish the good sites, though, from the rather poor sites. Rather poor sites are technically accurate for spelling etc. but often have cuts or don't indicate that they are only part of a text. In this sense rather poor sites can be more dangerous that really poor sites. And when you are dealing with literature, really poor, meaning mis-spellings, mis-scannings, missing words, lines or paragraphs, is really appalling.
