I agree that the damage is most likely fly excrement. In my experience, roach excrement appears as brown spots on books, but usually on the fore edges, or the part of the book opposite the spine and there would be additional signs of damage. We have some experience with fly excrement on manuscripts and paintings donated to the library and your picture looks identical. Staining will be dependent upon many factors inclusive of fly, their diet, the substrate of the material, and for the length of time marked. I would not say that these are markings from booklice or any other common library pest. Would be interested to know how well the manual removal goes.

The book is about 300 years old and was transported from Yemen to Austria long time ago and is now in the national library. I think it looks like fly droppings but I am happy for other suggestions!! We have no idea why this book was so attractive for the flies. The spots can be removed mechanically and have a small relief, bus some stains remain. Thank you very much, Pascal ---------------------------------------------------------------------- To send an email to the list, send your msg to [email protected]<mailto:[email protected]> To unsubscribe from this list send an email to [email protected]<mailto:[email protected]> and in the subject put: "unsubscribe" - no quotes please.
