I am happy to say that for many years I have been a member of the New York C.S. Lewis Society. The requirement has been $10 a year (best bargain going!!) which gives you a monthly bulletin containing a highly literate article or two which you will want to file away. I see that they have updated their website and have made available for purchase back issues of the Bulletin. The Society has also conveniently listed all books written by CSL, plus secondary works (books about Lewis and/or his writings), all of them linked to Amazon.com. And, of course, meeting topics are listed. Meetings are held the 2nd Friday of each month in New York City. Needless to say, most members of the NYCSLS live a distance from New York City and must content themselves with reading reports of the meeting in the Bulletin.
By reading the News link, I learned of a conference at Taylor University coming up the first week in June, a C.S. Lewis Summer Institute to be held at Williams College, and four free lecture telecasts titled "The Art and Faith of C.S. Lewis" made available by Trinity Episcopal Church in New York City. All very intriguing finds!
The lead article in the current (May-June, 2006) issue is by William J. McClain and titled "C.S. Lewis and the Reflective Christian." He rightly states, quoting Gene McGovern (a founding member of the NYCSLS), that readers appreciate C.S. Lewis because
They find that he has encountered their difficulties and dealt with them, that he has anticipated their objections and has articulated them better than they could. It is not too much to say that... he convinces his readers that however far they go he has been there before them and they are meeting him on his way back, back from having addressed these subjects that matter most and having thought them through to the end, to "the absolute ruddy end."
