==Examples==
[[File:Digitizing Estonian popular science magazine Horisont.jpg|thumb|Digitization of the first number of Estonian popular science magazine ''[[Horisont]]'' published in January 1967]]
The term is used to describe, for example, the [[image scanner|scanning]] of analog sources (such as printed [[photo]]s or taped [[video]]s) into computers for editing, 3D scanning that creates [[3D modeling]] of an object's surface, and [[Sound recording and reproduction|audio]] (where sampling rate is often measured in [[kilohertz]]) and [[Graphics pipeline#Modeling transformation|texture map]] transformations. In this last case, as in normal photos, the sampling rate refers to the [[Image resolution|resolution]] of the image, often measured in [[pixel]]s per inch.
Line 43:
"Digitization" is also used to describe the process of populating [[database]]s with files or data. While this usage is technically inaccurate, it originates with the previously proper use of the term to describe that part of the process involving digitization of analog sources, such as printed pictures and brochures, before uploading to target databases.<ref name="abc"/>
Digitizing may also be used in the field of apparel, where an image may be recreated with the help of [[Machine embroidery#Computerized machine embroidery|embroidery digitizing]] software tools and saved as [[Machine embroidery#

Analog signals are continuous electrical signals; digital signals are non-continuous. Analog signals can be converted to digital signals by using an [[analog-to-digital converter]].<ref>ICT Technologies. (2004, February 3). ''Analog vs. digital signals''. Chapter 3: Module 2: Communication Systems. Archived from the original on March 3, 2008. Retrieved on December 15, 2021, from https://tsapps.nist.gov/publication/get_pdf.cfm?pub_id=821701</ref>
The process of converting analog to digital consists of two parts: sampling and quantizing. Sampling measures wave amplitudes at regular intervals, splits them along the vertical axis, and assigns them a numerical value, while quantizing looks for measurements that are between binary values and rounds them up or down.<ref>{{Cite web |title=How do we convert audio from analogue to digital and back? |url=https://www.sciencefocus.com/science/how-do-we-convert-audio-from-analogue-to-digital-and-back/ |access-date=2023-04-14 |website=BBC Science Focus Magazine |date=11 October 2020 |language=en}}</ref>
Nearly all recorded music has been digitized, and about 12 percent of the 500,000+ movies listed on the [[Internet Movie Database]] are digitized and were released on [[DVD]].<ref>{{cite journal | doi=10.6028/jres.107.010 | title=The state of the art and practice in digital preservation | year=2002 | last1=Lee | first1=K.H. | last2=Slattery | first2=O. | last3=Lu | first3=R. | last4=Tang | first4=X. | last5=McCrary | first5=V. | journal=Journal of Research of the National Institute of Standards and Technology | volume=107 | issue=1 | pages=93–106 | pmid=27446721 | pmc=4865277 }}</ref><ref>{{cite journal | doi=10.1257/jep.31.3.195 | title=How Digitization Has Created a Golden Age of Music, Movies, Books, and Television | year=2017 | last1=Waldfogel | first1=Joel | journal=Journal of Economic Perspectives | volume=31 | issue=3 | pages=195–214 | doi-access=free }}</ref>
Digitization of [[home movies]], [[Photographic slide|slides]], and [[photographs]] is a popular method of preserving and sharing personal multimedia. Slides and photographs may be scanned quickly using an [[image scanner]], but analog video requires a video tape player to be connected to a computer while the item plays in real time.<ref>{{Cite web |title=Good-bye, VHS; Hello, DVD |url=https://www2.computerworld.co.nz/article/89569/good-bye_vhs_hello_dvd/ |access-date=2023-04-14 |website=Computerworld New Zealand}}</ref><ref>{{Cite web |last=Moses |first=Jeanette D. |date=2021-02-20 |title=How to digitize VHS tapes |url=https://www.tomsguide.com/how-to/digitize-vhs-tapes |access-date=2023-04-14 |website=Tom's Guide |language=en}}</ref> Slides can be digitized quicker with a slide scanner such as the [[Nikon]] Coolscan 5000ED.<ref>{{Cite web |title=Super COOLSCAN 5000 ED {{!}} Nikon |url=https://www.nikonusa.com/en/nikon-products/product-archive/film-scanners/super-coolscan-5000-ed.html |access-date=2023-04-14 |website=www.nikonusa.com |language=en}}</ref>

Another example of digitization is the [[VisualAudio]] process developed by the Swiss ''Fonoteca Nazionale'' in [[Lugano]], by scanning a high resolution photograph of a record, they are able to extract and reconstruct the sound from the processed image.<ref>{{Cite web |title=Swiss National Sound Archives |url=https://www.fonoteca.ch/index_en.htm |access-date=2023-04-14 |website=www.fonoteca.ch}}</ref>
Digitization of analog tapes before they degrade, or after damage has already occurred, can rescue the only copies of local and traditional cultural music for future generations to study and enjoy.<ref name=":114">{{Cite journal |last=Breeding |first=Marshall |date=2014-11-01 |title=Ongoing Challenges in Digitization |url=https://librarytechnology.org/document/20128 |journal=Computers in Libraries |language=en |volume=34 |issue=

The prevalent [[Brittle Books Program|Brittle Books]] issue facing libraries across the world is being addressed with a digital solution for long term book preservation.<ref>Cloonan, M.V. and Sanett, S. "The Preservation of Digital Content," Libraries and the Academy. Vol. 5, No. 2 (2005): 213–37.</ref> Since the mid-1800s, books were printed on [[pulp (paper)|wood-pulp paper]], which turns acidic as it decays. Deterioration may advance to a point where a book is completely unusable. In theory, if these widely circulated titles are not treated with de-acidification processes, the materials upon those acid pages will be lost. As digital technology evolves, it is increasingly preferred as a method of preserving these materials, mainly because it can provide easier access points and significantly reduce the need for physical storage space.
Cambridge University Library is working on the [[Cambridge Digital Library]], which will initially contain digitised versions of many of its most important works relating to science and religion. These include examples such as Isaac Newton's personally annotated first edition of his ''[[Philosophiæ Naturalis Principia Mathematica
Google, Inc. has taken steps towards attempting to digitize every title with "[[Google Book Search]]".<ref>{{cite book|url=https://books.google.com/|title=Google Books}}</ref> While some academic libraries have been contracted by the service, issues of copyright law violations threaten to derail the project.<ref>Baksik, C. "Fair Use or Exploitation? The Google Book Search Controversy," Libraries and the Academy. Vol. 6, No. 2 (2006): 399–415.</ref> However, it does provide – at the very least – an online consortium for libraries to exchange information and for researchers to search for titles as well as review the materials.

== Challenges ==
Many libraries, archives, museums, and other memory institutions, struggle with catching up and staying current regarding digitization and the expectation that everything should already be online.<ref name=":142">Greene, M. A. (2010). MPLP: It's not just for processing anymore. ''The American Archivist, 73''(1), 175-203.</ref><ref name=":152">{{cite journal | doi=10.1108/DLP-06-2017-0020 | title=Ramping up | year=2018 | last1=Lampert | first1=Cory | journal=Digital Library Perspectives | volume=34 | issue=1 | pages=45–59 }}</ref> The time spent planning, doing the work, and processing the digital files along with the expense and fragility of some materials are some of the most common.
=== Time spent ===
Line 131:
=== Expense ===
Cost of equipment, staff time, metadata creation, and digital storage media make large scale digitization of collections expensive for all types of [[cultural institution]]s.<ref name=":162">{{cite journal | doi=10.5860/rbm.13.1.369 | title=Balancing Boutique-Level Quality and Large-Scale Production: The Impact of "More Product, Less Process" on Digitization in Archives and Special Collections | year=2012 | last1=Sutton | first1=Shan C. | journal=RBM: A Journal of Rare Books, Manuscripts, and Cultural Heritage | volume=13 | issue=1 | pages=50–63 | doi-access=free }}</ref>
Ideally, all institutions want their digital copies to have the best image quality so a high-quality copy can be maintained over time.<ref name=":162"/> In the mid-long term, digital storage would be regarded as the more expensive part to maintain the digital archives due to the increasing number of scanning requests.<ref name="Duran Casablancas">{{Cite journal |last1=Duran Casablancas |first1=Cristina |last2=Holtman |first2=Marc |last3=Strlič |first3=Matija |last4=Grau-Bové |first4=Josep |date=2022-10-12 |title=The end of the reading room?

=== Fragility of materials ===
Line 151:
=== Non-traditional staffing ===
Many institutions have the option of using volunteers, student employees, or temporary employees on projects. While this saves on staffing costs, it can add costs elsewhere such as on training or having to re-scan items due to poor quality.<ref name=":152" /><ref>{{cite journal | doi=10.1108/DLP-07-2017-0024 | title=Staffing with students | year=2018 | last1=Skulan | first1=Naomi | journal=Digital Library Perspectives | volume=34 | issue=1 | pages=32–44 | url=https://digitalcommons.morris.umn.edu/library/7 }}</ref>
