The Secret Oral Teachings in Tibetan Buddhist Sects by Alexandra David-Neel & Lama Yongden, City Lights Books (1972).
One of the additional pleasures of buying old books besides finding something out-of-print (or, it has to be said, something cheap) occurs when those books still possess traces of their previous owners. A recent posting on The Other Andrew’s page concerned book inscriptions, something any book collector will be used to seeing. Less common are the objects which slip from the pages when you’ve returned home. There are several categories of these.
I have a substantial collection of bookmarks proper, from embossed strips of leather to the more mundane pieces of card of the type that bookshops frequently give away. But I also make a habit of using odd inserts to mark a place as did the previous owners of these volumes. The City Lights book (above) came with a very fragile leaf inside it which may well be as old as the book. Another City Lights book I own, the Artaud Anthology from 1965, included a newspaper article about Artaud. Newspaper clipping inserts are discussed below.
