The CILIP Rare Books and Special Collections Group holds regular training events on various matters pertaining to rare books and special collections. Yesterday Senate House Library hosted a Group event devoted to an element of advocacy – always a popular topic – namely, an account of editing treasures volumes. This was a behind-the-scenes description of editing Senate House Library, University of London: how items were selected and contributors approached, an exposition of the working relationship between author/editor and publisher, the aims and limitations of writing a library’s history for such a purpose … in short, an outline of the whole process. It was a great way to talk about our treasures and our treasures volume, to raise the profile of the book, and hopefully to help others who are considering producing a treasures volume about their collections.
