`  == External links ==  first comment/question:  this link—``List of Seth Sessions by Mary Dillman,`` and this link—``Index of Eleven Seth Books by Sue R. Williams,`` both go to the same webpagethe front page of a website put up by Mary Dillman that is Seth related.  it doesn't link directly to any sort of list.  next comment/question:  the last 4 links are all for websites/pages for a ``Lynda Dahl.``  this surprised me, as i didn't remember seeing that name anywhere in the article.  a search led me to ref/source #15, which is: ``ESP Power, by Jane Roberts (2000) (introductory essay by Lynda Dahl). ISBN 0-88391-016-0``  the relatively recent publication date caught my eye.  i did a search for the book and found a ``Fells' Official Know-it-all Guide to ESP Power,`` first published in 1974, then in 1997, and then in 2000.  ``How to Develop Your ESP Powers`` was published in 1966 by Pocket Books. (which means this item is incorrect in the ``Complete writings`` list, which lists the publisher as ``Federick Fell.``  i found it on AbeBooks, and the cover clearly shows ``Pocket Books.``  and, at any rate, i'm fairly certain it should at least be ``Frederick.``)  at any rate, i could not find a single site that had this 2000 reprinted book available (store or library) that listed an introduction, let alone an introduction by a Lynda Dahl. nor was an introduction mentioned on those pages that had the original 1966 book available.  which leads me to ask if this can be verified?  if not, i question the inclusion of it in the ``References`` item.  and, whether the introduction is verified or not, i question having 4 external links for a different person on an author's WP article.  it starts to come across as self-promotion, so i bring it here for discussion. Note: the final link—``Seth/Jane Roberts Books and Info``—is to a Facebook page maintained by Linda Dahl.  `
