Many books have material added that is not inherent to the original publication. The two most prevalent categories are manuscript annotations and inserted ephemera. Houghton has developed a variety of routine local strategies for addressing such classes of material.

Printed items often contain manuscript markings. Routinely, these are noted in the 561 or 562 of the holdings record and, if applicable, the name of the former owner or annotator is traced in the bibliographic record in an added entry, with the appropriate relationship designator(s). (See RDA Appendix I, the RBMS list of relationship designators, and MARC guidelines and terms for vocabulary and usage.) However, on occasion, an item will often be found to contain significant manuscript additions or insertions. Treat these as noted below.

In some cases, loose material is intrinsic to or otherwise associated with the publication: a purposefully loose leaf in an artist's book, for example, or a former owner's notes or correspondence referring to the text. In these instances, keep the material with the book and request that a case be made; the routing slip should have the phrase "(LOOSE MATERIAL)" added on the line below the call number so that end processing can include this warning on the tab or spine label.
Note the presence of loose material in a 562 note, if the bibliographic record does not already describe it; and in the case of manuscript material, include the local 'Manuscripts in books' form/genre term. Retention of loose material with books is situational, and consultation with the appropriate curator is often advisable.
