Dear all,
Thank you for your replies to my enquiry about what to do with a pressed flower found inside a rare book.
Firstly, I can report that the specimen found inside our 1597 Gerard ‘Herball or generall historie of plantes’ (https://twitter.com/RCPmuseum/status/534358244052193280) has been identified as a legume, most likely most likely to be bird’s-foot trefoil (Lotus corniculatus).
DISPOSAL
Most libraries are keeping specimens. Two replies mentioned that they might dispose of them if they were disintegrating, or if they were of no apparent relevance to the book in which they were found.
DOCUMENTATION
Most replies mentioned documenting the specimens in the catalogue record. One specifically said that they don’t document. Those who gave details specified the 561 field or, in once case, a 590 field. For archives records, the description field was mentioned in one reply.
Examples:
• http://library.cardiff.ac.uk/vwebv/staffView?bibId=1021638
• http://library.cardiff.ac.uk/vwebv/staffView?bibId=1036394
• http://library.cardiff.ac.uk/vwebv/staffView?bibId=1061594
• http://library.cardiff.ac.uk/vwebv/staffView?bibId=1057775
• http://library.cardiff.ac.uk/vwebv/staffView?bibId=942944

STORAGE INSIDE THE BOOK
The great majority of respondent indicated that they would keep the specimen inside the book in the location in which it was found inside an appropriate enclosure, if the added thickness would not cause strain to the binding.
Another common alternative was to place the specimen in an enclosure at the back or front of the book, or to place it in the box of a boxed item.
Some libraries with specialised collections containing a lot of material of this kind have enclosure made by a conservator that are then either mounted on guards in the book, or kept with the book in another suitable manner.
The library that didn’t document specimens found also noted that it doesn’t enclose them, either.
At least one respondent suggested labelling the enclosure to indicate where it belongs – a sensible idea!
ENCLOSURE MATERIALS
Melinex and acid free tissue were both used in roughly equal numbers of replies. Melinex has the benefit of allowing you to see the specimen, and to see through the enclosure to the page beneath. Acid free tissue is rather thinner.
Two more involved enclosures were suggested by one conservation officer:
• A ready made product from Preservation Equipment, 'Herbarium specimen sheet protectors': http://www.preservationequipment.com/Store/Products/Archival-Storage/Natural-History-Collection/Herbarium-Specimen-Sheet-Protectors
• Making a bespoke enclosure: put the flower on artists water colour paper, cover with tissue and place in a polyester storage bag with a piece of desiccant paper for moisture absorbing then remove the air and seal.
But this same conservator also notes that leaving plants between the pages of a book, has been done successfully for centuries, and you can tell if the specimen has been causing damage.
STORAGE OUTSIDE THE BOOK
Several responders noted that they would store the specimen separately from the book if it was harming the paper or binding, or if there are too many specimens in one volume to be kept in place in the book.
Separately stored specimens are stored with the book in a folder or envelop shelved next to the book.
Louise Roberston, a conservator at the University of Glasgow, made individual pockets to store plant material found in Fuchs’ De Historia Stirpium, as documented in this blog post: http://universityofglasgowlibrary.wordpress.com/2013/09/02/a-blooming-binding-blog-part-4/
There’s also guidance available on making herbarium samples:
• Royal Horticultural Society: http://www.nccpg.com/Conservation-resources/RHS-Guide-to-making-herbarium-specimens.aspx (pdf link)
• Royal Botanic Gardens and Domain Trust, Australia: http://www.rbgsyd.nsw.gov.au/plant_info/identifying_plants/processing_plant_specimens/Preserving_plant_specimens
AND FINALLY
This is a lovely blog post about a specimen found in a war memoir in Surrey: http://www.exploringsurreyspast.org.uk/sherriff-blog-1/
Thank you again to everyone who took the time to reply.
Best wishes,
Katie
