The three pronged approach to the Early Irish Manuscript project has afforded us the opportunity to focus our attention on key modern disciplines in relation to manuscript study; conservation, research and digitization, all of which require close scrutiny of the material and content. In addition we have taken full advantage of the extended time period working with each of the manuscripts to search for clues of their past life and attempt to answer such questions as: where and when was it written; how was it used; and what did it look like when it was first bound (this is a familiar question for early medieval books, as less than a handful of insular manuscripts are still contained inside their original bindings)? There are quite often subtle and not so subtle clues to assist in answering these and other codicological questions if you know what you are looking for.
Sewing (fig. 1): How the quires of early medieval manuscripts were sewn together varied geographically and chronologically and even though the original sewing has likely long since been replaced, often more than once, evidence of its existence, such as holes in the backfolds of the quires or even ghost traces of impressions in the vellum can yield useful clues, such impressions might even inform us of the thickness and make-up of the thread. If you are really fortunate, original thread fragments may remain trapped under a later sewing.
