As with other National Endowment for the Humanities programs, this is a partnership program. This means that institutions such as archives and libraries must apply for grants in order to participate. After applying, the institution is rigorously reviewed. Should the institution be accepted, they are required to share at least 33% of the program's costs. Unlike the other National Endowment for the Humanities preservation funding initiatives, there is no requirement that an institution in each state must be awarded a grant. The projects are largely run at the state level with the National Endowment for the Humanities providing methodologies, assuring a standard level of quality, and connecting the efforts of the various institutions. In order to be awarded a grant as part of the Brittle Books Program, institutions had to abide by five basic conditions:
*1. That they abide by the national standard
*2. That they create three copies of all material: a master negative, a print negative, and a service copy
*3. That a record adhering to national standards be entered into a national bibliographic database
*4. That interlibrary loan copies be readily available
*5. That storage conditions meet that of the national standard [ [http://www.nhalliance.org/testimony/1995/95testimony-pbattin.html NHA Testimony: Patricia M. Battin, 31 March 1995 ] ]
Preservation Issues
Deacidification
While there is a deacidification [http://en.wikipedia.org/wiki/Mass_deacidification] method that can successfully lower the acidity in Brittle Books, many public libraries do not have the funding to implement standard programs to halt the slow burn taking place in these institutions. Some repositories have the resources to send books for a deacidification wash in stages, others have access to some sort of digitization method such as microform [http://en.wikipedia.org/wiki/Microform] or PDF, and others utilize the ability to make preservation-quality photocopies.
Deacidification washes are usually a viable option for most repositories as books can be sent in bulk; however, only books of excellent physical quality may be sent. The wash process is rather aggressive and any deformities in a book may cause damage to already brittle specimens. Therefore, libraries would have to repair those books in less than desirable condition - specifically elements of the binding, leaf attachments, and text attachments - making the reasonable deacidification wash more expensive through conservation efforts.
Paper Splitting
Another option is paper splitting, [ [http://www.loc.gov/preserv/papertreng.html MDEP Paper Strengthening Pilot Program 2003-2005 (Preservation, Library of Congress) ] ] which dissects a book by its leaf and text attachment and treats each sheet of paper individually. Supervised by a book conservator, a paper conservator, and a conservation specialist, pages are literally pulled apart - fronts from backs - and a piece of alkaline paper is placed in between. The acid pages are then sandwiched back together with a non-acid buffer between them to slow the deterioration process. However, only ZFB (the Zentrum für Bucherhaltung) [ [http://www.zfb.com/en_version.php Mass Deacidification and Conservation for Libraries, Archives and Museums from one source ] ] offers this procedure (also called mechanical paper splitting). They claim the process is so refined, they have successfully split cigarette paper. Washes will de-acidify the paper though they will remain brittle; but paper splitting increases the strength and flexibility of the paper via the extra new sheet of buffered paper and the ZFB process includes de-acidification washes.

Microform
Microform is a reasonable option for Brittle Book preservation mainly because microfilm can last for 500 years, so long as it is stored in proper conditions and a microfilm reader is accessible. Even microfeche is easier to store than microfilm, providing strict organization methods are practices so sheets are not misplaced from the filing system. Despite its proven record of durability, microform is not a preferred method of digitization because of accessibility issues. In an increasingly electronic world, microform is becoming extinct due to its inability to be accessed over the Internet.
Digitization
Even though computer files usually carry around a five year shelf life, complete digital conversion of physical items is the preferred method. However, public libraries usually cannot afford the server space required for such large electronic files. Moreover, digitizing Brittle Books can cause problems with respect to copyright law. While the library is authorized to make a copy of a book it cannot obtain through reasonable means, having a digital copy offers the possibility of unauthorized distribution if circulated in this format.

Photocopies
Many repositories, such as the University of Kansas, [ [http://www.lib.ku.edu/preservation/BrittleBooks.shtml KU Libraries: Brittle Books Program ] ] opt for preservation-quality photocopies. A list-serv [ [http://www.lib.ku.edu/preservation/Brittle.shtml KU Libraries: Brittle Books Program ] ] is utilized for the posting of titles so a consortium of libraries can benefit from a reduced cost in replication so they may maintain their circulating collections. Maintained by OCLC, the submissions are processed at the OCLC Preservation Service Center and OCLC retains the digital copies produced as to defer any copyright issues away from the repositories subscribing to the service.
Future
As libraries move into the digital era, preservation practices attempt to move with them. Current and future projects in preserving brittle volumes are more likely to involve scanning and digitization rather than microfilming. A recent example of this is the "Digitizing America's Imprints" project at the Library of Congress which recently received a $2 million grant.
