Paper and Reformatting Chapter 2: Reformatting
2
Hopeless Cases and Indentification: To Replace or Reformat....... That is the 010 101
3
Hopeless Cases and Indentification: ► Books that require an unreasonable amount of work to repair ► Knowing you options: Replacement Reformatting
4
Replacement: ► Activities that result in the receipt of a duplicate of the irreparable volume through routine acquisition and gift processing ► This can include in-print vendors, antiquarian, e-bay, microform publisher
5
Reformatting: ► Activities that involve special efforts to have the text transferred to another medium in order to preserve the text ► Transfer to paper, microfilm and digital images
6
Brittle Books Programs: ► Programs are based on a couple of questions: Based upon the library’s collecting policy. Must the book be considered in its original format as a rare book or artifact?
7
Research Questions ► What treatment decisions should be made? ► Who should make the decisions? ► Should preservation staff play a role in the decision. ► All answers dependent upon type of organization. ► Base our decisions on a Search Results sheet-Who else has the item?
8
What about Copyright? ► Law allows for preservation of copyrighted works, “solely for the purposed of preservation and security” Section 108 ► Include a notice or disclaimer indicating copy ► Reformatting is NOT to be used as acquisition ► Archives – Donor restrictions
9
Overview of Microfilm
10
Why Microfilm? ► It was used as an important part brittle books programs ► Predicted long life of up to 500 years ► Huge infrastructure developed for the creation and viewing of microfilm ► In 1989, Congress authorized NEH to implement a 20 year initiative to preserve intellectual content via microfilming. This ended in 2009
11
Why microfilm? (continued) ► No matter how you feel about microformats it is important to understand the procedures and development of microfilming and preservation facsimiles: ► Because: As in the case of facsimiles, many patrons still prefer to have a copy in their hands Libraries & archives must deal with microfilm and any continuing projects in their collection
12
Microfilm: ► Adhere to RLG standards ► Creation of three generations Preservation copy or archival copy Duplicate Use or service copy
13
Microfilm (continued): ► Silver Halide – silver gelatin microfilm with a polyester base Stable metal Image on silver film is metallic silver Tested lifespan 500 years Scratches easily Archival copy
14
Microfilm (continued) ► Diazo Film: Intended for service copies Polyester base Life expectancy of up to 50 years because of possible fading Chemical duplication using Ammonia Blue Black image is produced
15
Microfilm (continued) ► Vesicular Film Also intended for service copies Polyester base Life expectancy 10 – 20 years Not vulnerable to fungal growth Duplication by heat and emulsion to emulsion contact White image on blue background
16
Microfilming Process: ► Decisions: Outsourced or in-house? Contracts and RFP’s ► Vendor Question Examples: What are the costs? Do you allow for visits to the facility? Preservation guidelines? Type of film?
17
Preparation of Material for Microfilming: ► Bibliographic searching ► Database searching – record keeping ► Collation ► Reel programming Source: http://library.furman.edu/specialcollections/borrowing_ microfilm.htm
18
Microfilm ► Typically get 600 – 900 frames in a reel ► With books, tend to get 2 pages per frame ► With oversized documents, 1 page per frame ► The number of frames on a reel depends on the orientation and size of the originals being filmed
19
Evaluation and Quality Control ► Methylene blue tests to check amount of residual thiosulfates on film 3 rd party ► Technical – cannot allow for scratches unless it is on leader - 6 splices are allowed ► Quality Index- at what level do you see the “e” and its relation to the linepair ► Bibliographic – Targets are in order
20
Filming Process: ► Reduction ratio desired: Desired is 12:1 or 14:1 ► Microfiche – 16 mm, 24:1 ► Density – degree of blackness ► Image presentation: Cine or comic mode Micro-File MRD-2 shoots 35mm and/ or 16mm film. Source: http://www.worldmicrographics.com/Planetar y_Microfilmers.html
21
Digitization ► The more popular reformatting choice ► Many projects that used to be done on microfilm have evolved to become digitization projects ► More grants are now issued for digital projects Source: http://www.imagewarescanner.com/index. php?id=164
22
Reformatting: Digitization vs. Microformat ► Still need to collate the items ► Still need to adhere to current best practices and standards ► Still need to consider access to the surrogate ► Still need bibliographic control ► If the items aren’t unique, investigate if someone else has already done the work
