Labeling objects


 Marking an object, usually with an accession number, provides a link between the object and the information about it.  All museums and archives label their material so the link to the provenance (history) or provenience (origin) of the object or collection is maintained.  Obviously there are ways to do this that limit the damage to the object.  Again remember anything done to an object must be reversible.  I’ll only cover a few of the types of objects and how to label without damage. 

Photographs – Labeling photographs with the date and people and places is a pretty common practice.  Unfortunately many people write on the photograph or on the back with a ballpoint pen. That makes the photograph most unhappy - not reversible and very damaging.  Leaves indentations and chemically active ink.  The best way is to mark photographs on the back with a graphite pencil.  These can be found at any art supply or craft store.  Graphite will write on the back of photographs even if they are shiny photo paper. (It can smudge so don’t rub it.) Usually museums and archives will mark an accession number on the back in a corner of the photograph.  As noted above the accession number links to an inventory with information about the photograph.  Another way to mark photographs (again in an unobtrusive corner on the back) is with a pen containing India ink, which is inert and will not damage the photograph.  The problem with using a pen is the issue of reversibility.   In some instances the sleeve used for storage can be labeled instead of the photograph.  For scanned images, the metadata provides the information about the photograph.

Paper – Usually the file folder is marked in pencil or with acid free typed labels, but if a paper is to be marked you need to use a 2B pencil and find an unobtrusive corner usually on the back. Using library labels common on books and magazines is a no-no.  It's not reversible and the glue is acidic. If the paper is sleeved then the identification can be written onto the sleeve instead of the paper.   

Objects – Archives have objects too.  These also should be marked following the standards set by museums.  (Archaeologists also mark objects to link to excavation information and they should follow museum standards too.)  The accepted way is to use a substance called Paraloid B-72 which is inert and looks like clear nail polish.  You can also get a white variety to use on darker objects after first coating the spot for the label with Paraloid B-72.  The labeling number is written with India ink.  Once this has dried it is covered with another thin layer of Paraloid B-72

Textiles – If the textile must be labeled, a label made of cotton or linen is sewn in an unobtrusive place.  I use the cotton tape sold at sewing stores. Remember it must be material that has no chemicals, not manmade fabric. I sew it on with cotton thread.  Again the numbering is in India ink.  Be careful to use a pen that it doesn’t run on the label.  Most archival supply companies like Gaylord have the supplies one needs.

The web offers numerous explanations of labeling – probably more clearly than I just did.  Here are some examples:
