I have now updated the Studies on Edward Lear page with several articles mentioned in this post, and a new one:

Woddis, Anna. “’More or Less a Sorrow’: Some Observations on the Work of Edward Lear.” Pictures at an Exhibition (Psychology Revivals): Selected Essays on Art and Art Therapy. Eds. Gilroy, Andrea and Tessa Dalley. 2014 ed. London: Routledge, 1984. Google Books preview.

Meanwhile, Robert Peck has written to announce a new book on Edward Lear; here is the relevant passage in his e-mail:

I am happy to report that in January I signed a contract with David R. Godine, a Boston-based publisher, for a book on the natural history paintings of Edward Lear.  Sir David Attenborough has agreed to write a foreword.  The book will contain a detailed account of Lear’s natural history career and include many paintings that have never before been reproduced from the Houghton Library at Harvard and from many public and private collections in the U.S., the U.K., and Canada. It will include information contained in my Harvard Library Bulletin essay of 2012, but additional information as well.  The book will probably not be published until late next year or early 2016.  I will keep you up to date on its progress.

Also, Stephen Duckworth announces that in May he will be giving a lecture on Lear in Crete in view of the 150th anniversary of his visit, which you will be able to follow on the Diaries blog. He also reports on rumours of a possibly coming Edward Lear Society. Details on both as soon as I get them.

Finally, the next issue of the New Escapologist should have a very short note by me on Edward Lear and the Absurd.
