Best Practices

Storage

When not actively working on materials they should be stored on shelves or on pallets when space is limited. Don’t leave boxes directly on the floor, in case of leaks, flooding, and pests. Boxes should not be stacked more than four boxes high.

Large and/or heavy items (e.g, record cartons or oversize flat boxes) should not be placed above shoulder-level. 

Handling and Lifting

Boxes Record cartons used in the Archives can Distinctive Collections generally weigh up to 40 pounds in most circumstances. .

  • Know your safe handling limits:

    • If a box is heavy, ask a second person to help you lift it, or unload contents into 2 boxes.

    • Never lift materials weighing more than 50 pounds by yourself.

    • Only move 4 to 6 boxes on a rolling cart at a time.

  • Lift with your knees rather than your back.

  • Do not twist while lifting.

  • When lifting and carrying an object hold it close to your body not higher than chest level.Do not twist while lifting.

  • Push rather than pull when moving heavy objects.

  • Know your limits and move only 4 to 6 boxes on a rolling book truck at a time.

Storage

Don’t leave boxes directly on the floor, in case of leaks, flooding, and pests. Boxes should be put on pallets or shelves. Large and/or heavy items (e.g, record cartons or oversize flat boxes) should not be placed above shoulder-level. 

Tools and Supplies (that come into contact with distinctive collections)

  • Supply stations include a legal and letter size set of folders, subfolders, mylar, flags, erasers, a micro spatula, and rulers. These stations are supplied by Wunsch Conservation Lab and when they are empty we should notify Wunsch to replenish. These are located in 14N-118 basement areas (2 in 14-0710, 1 in 14-0627), 1 at the ASC, and 1 in the 14N-118 mezzanine.

    Folders should always fit the box without leaving excess space on the sides.

    Avoid reinforced file folders as brittle materials can catch on them and break. When using reinforced folders, reverse fold them so that the seam is on the outside of the folder.

    Rehousing Materials

    Processing considerations

    Foldering

    • Folder size must match box size. Any subfolders or L-sleeves used must be the same size as the folder.
    When do we folder?
    • Retain all original folders .Refolder Pendeflex but keep original titlewhen possible.
    • If original the original folder has noticeable physical weakness replace with new folder.
      • If there is information on the original folder keep it and put it in a new folder.
    • Materials stored in hanging files (i.e., Pendaflex) should be refoldered. Retain original title, and place the label in the folder.
    Bindings
    • .

    The default orientation for folders within record cartons is letter size orientation. If there are materials that are larger than letter width and fit into legal size folders, the entire box can be shifted to legal orientation. All folders in a box must be the same size. If there are only a few legal size records, individual folders may be added to a legal size manuscript box.  You will want to note what box they originally were removed from so that they can be intellectually integrated in the resource record. Oversize materials should be placed in flat boxes or in flat file storage.

    Bound Materials (books, albums, volumes)

    When you encounter books or bound volumes in an archival or manuscript collection they may be foldered and stored “with the spine down (storing a book with the spine up may cause the text to pull out of the binding due to its weight).” (NEDCC). Bound materials should always be stored spine down – text blocks may detach from the binding when stored spine up.

    Scrapbooks, albums, and heavy or oversize volumes should be stored flat. If they fit in a Paige box they can be stored flat in that, but if they are larger than a Paige box they should be moved to a flat box.

    Interleaving - use subfolders from conservation

    • Newspaper clippings

    Slide and Split Ring Binders and Other Adjustable Bindings

    Adjustable bindings (split ring binders, Acco binders, slide binders) may be removed as needed. Remove any bindings that are damaging or make the use of materials difficult. Materials removed from these types of bindings should be kept together in folders or subfolders as appropriate.

    Metal Fasteners

    We do not routinely remove metal fasteners from material, but we may elect to remove them if the fasteners are causing significant damage to the material or to their folders or other housing.

    Remove paper clips by bending the smaller loop upwards. Support the back side of the clip while you work. Never slide a paperclip off.

    Always remove staples with a microspatula.

    • Use your opposite hand to support the paper around the staple as you work.

    • Work on the back side of the paper.

    • Use the blunt end of the spatula – only use the pointed end to get a difficult staples started. A heavy duty microspatula is also available for heavy staples.
    • Bend up one prong of staple at a time.

    • Support the paper around and over the opposite prong when bending the first prong up

    • Gently remove the staple from the front side of the paper

    For instructions on disposing of sharps, see Disposal decision guide.

    Tip

    See: NEDCC, "Removal of Damaging Fasteners from Historic Documents" for more instructions on removing fasteners.

    Newspaper Clippings

    If  a collection is processed If processing to a level 3 or 4, archivists may want to interleave place newspaper clippings with paper (printer paper is fine)in subfolders, unfolding clippings if they are folded. If the clippings are friable or damaged, use an L-sleeve in place of a subfolder. Depending on the collection it may also be appropriate to move oversize clippings into legal or oversize folders.

    Photographs (prints, negatives, slides)

    In general we do not need to rehouse prints, negatives, and slides if they are in original housings such as separate boxes , or envelopes from the developer. We may want to add some preservation measures when they are in a folder with other material that they should be separated from - for example (e.g., a single negative or print within a folder of newspaper clippings). If processing to a level 2 or 3 and a single photograph is found in a folder, one can create an envelope for the photograph using printer paper that would provide some protection. One could also interleave photographs use a subfolder to provde protection. Photographs may also be interleaved with paper. If there is one or a few loose slides, they should be put into a slide sheet and kept in their original location.

    If processing to a level 3 or 4 it may be appropriate to put prints, negatives, and slides into specifically created sleeves and separate them from the rest of the collection.

    Telegrams

    Anything super fragile or acidic

    and Other Fragile and/or Acidic Materials

    Acids in poor quality papers (e.g., newsprint, telegrams) can migrate to other materials and cause damage. Use subfolders or L-sleeves to protect and isolate materials. If using an L-sleeve make sure fragile materials are supported during insertion.

    Transparencies

    If transparencies are sticky, moldy, or smelly smell bad they should be discarded. Otherwise they can be foldered similar to any other pieces of paper in a collection. Transparencies are heavier than paper and because of this if there are a lot of transparencies they should be housed in manuscript boxes rather than record cartons.

    Physical

    legacy media (substrates that hold digital media

    Legacy Media (Substrates That Hold Digital Media)

    Note these in the description (at file and/or collection level)

    Metal Fasteners

    We do not routinely remove metal fasteners from material, but we may elect to remove them if the fasteners are causing significant damage to the material or to their folders or other housing

    If removing staples:

    • Use the preservation spatula to remove staples

    • Use your opposite hand to support the paper around the staple as you work

    • Work on the back side of the paper

    • Bend up one prong of staple at a time

    • Use the blunt end of the spatula (only use the pointed end to get a troublesome staple started)

    • Support the paper around and over the opposite prong when bending the first prong up

    • Gently remove the staple from the front side of the paper

    For instructions on disposing of sharps, see Disposal decision guide.

    Textiles

    Textiles should be placed in flat boxes only with other textiles.

    Options include:

  • Flattening or unfolding minimally (maybe folded in half)
  • If

    Textiles may be unfolded or left minimally folded (i.e., in half). Contact the Wunsch Conservation Lab for large textiles, or if the object warrants more attention than flattening and fitting in a flat box

    conservation can put tissue paper in the material
  • For large textiles consult conservation
  • Use textile boxes that are housed at the ASC
  • . Textile boxes for use are kept at onsite storage.

    Frames

    Frames should be removed from materials when appropriate. Use your best judgement. If materials are fragile, intricate, fused to the frame, or would be difficult to remove the framed object can be placed in a box, with or without a folder. 

    Frames

    If easy yes de-frame, if medium use your archival judgment, if difficult it is probably not necessary to de-frame. Final decision is up to the archivist. When considering mat folder size take into consideration if item can be removed from matting easilyeasily — materials may be adhered to the mat.

    Easy to remove = Can do yourself using no to minimal tools. Some

    Some frames may be easy to remove with or without minimal tools. Pay attention to the construction, some frames use hardware that is easy to remove by pushing up or down

    . It is reusable and de-framing should be easy and cause no damage to the frame, hardware, or the item. The frame can

    , or are held together only with screws. These frames may be reused by staff (or offered

    to a free pile in basement, or reuse event in Stata. Most items that are framed in this type of frame should be removed from the frame, foldered, and added to a Paige, manuscript, or flat box.
  • Medium difficulty = Frame backing needs to be torn - often cut using scissors or box cutter. With this type of frame it is often difficult to impossible to use the frame again. In most cases we will still de-frame the material.
  • Hard to remove = This is if the frame and item are very fragile and de-framing could harm the material, or if the frame is very intricate and it will be very time consuming to remove the frame. In this case the object can be placed in a box and depending on thickness with or without a folder.
  • though the reuse list, reuse drop spots, or Choose to Reuse events).

    For frames with a dust cover, remove the backing with a box cutter, being careful to not cut beyond the paper backing. Mat boards will often be held in place using small nails or framing points. Remove these fasteners with pliers, or bend up using a microspatula. Use care — framing points are sharp on all sides.

    When finished, glass should be separated into a box. Contact Tools for de-framing: You may need scissors, gloves, pliers, and a sharps container. Glass should be separated into a box and when there is a box full contact EHS to remove. See the Disposal Guide for more. 

    Folder orientation

    The default orientation for folders within boxes is letter size orientation. If there are materials that are larger than letter width and fit into legal size folders, the entire box can be shifted to legal orientation - if you do that every folder within the box needs to be legal size. Another option, if there are only a few legal size records, is to remove those folders and add to a legal size manuscript box. You will want to note what box they originally were removed from so that they can be intellectually integrated in the resource record.

    Folder size must match box size. And all subsequent materials - subfolders, polyester sleeves - must match folder size. For example, use legal size folders and polyester sleeves in legal size boxes or with legal size orientation in Paige boxes.

    Refoldering Pendaflex (hanging folders)

    Many people keep their records in Pendaflex folders in file cabinets. These folders are often letter sized with metal supports that allow the folders to hang in file cabinets. They do not fit into Paige boxes when oriented by letter size. Materials should be removed from Pendaflex folders and put into letter or if needed legal size folders. Remove the original label from the Pendeflex and place inside the folder, copy the original title to the folder title.

    Digital Disk Images

    Often we do not want to retain full disk images but only the files within or a subset them. In order to extract the files from the disk images, there are a few tools that we can use. You can find an overview below and the documentation for each on the Disk image extraction page and the steps to follow afterwards.

    The main tool for extracting disk images in the CCA tools Disk Processor. It is used on all disk images when possible. This will extract the files and you can choose whether you want to retain the disk image or not. It will also create a number of reports that will also be used in surveying the collection.

     The HxC Floppy Emulator is a tool that allows for opening of floppy disk images, browsing some types, exporting files, and convert disk image formats. It also allows you to visual the tracks of a disk image, to see where the errors/data are. If CCA disk processor has failed or you have .raw disk images that you couldn't extract files from, you can load the raw files and try to extract files created on various DOS systems.

    HFS Explorer allows you to mount and export files from HFS disks (Macs) individually. This is a back up to CCA tools disk processor (which uses this behind the scenes) or if you want to check to see if floppy disk imaging was successful.

    Refoldering Binders

    Photocopying Material

    We do not routinely photocopy original material. In most instances you will either keep the original material or discard it after copying the needed information. Exceptions to this is However, when there is information on original housing that you want to preserve but the actual housing can be discarded - for example if there is an oversize envelope with a note written on it and you aren’t sure what it means, you could photocopy the note (e.g., notes written on a binder) , photocopy the material and insert the photocopy in the folder with the material originally housed in the envelope.

    Cleanliness of workstations

    When not actively working on materials they should be stored on shelves. All materials should be stored in boxes on shelves.

    Keeping workstations clean increases

    Recording Preservation Actions

    Physical Characteristics and Technical Requirements 

    or subfolder with the related materials.

    Recording Preservation Actions

    Any preservation actions undertaken should be documented in the collection description. Most actions should be documented in Processing Information notes. Notes on preservation concerns or special handling needs should be documented in the Physical Characteristics and Technical Requirements note. Notes should be placed at the collection level and at the file or item level for any special concerns.
