Most libraries have materials arranged in a specified order according to a [[library classification]] system, so that items may be located quickly and collections browsed efficiently.<ref>{{cite web |title=Library classification |url=https://www.britannica.com/science/library-classification |url-status=live |archive-url=https://web.archive.org/web/20210416234738/https://www.britannica.com/science/library-classification |archive-date=16 April 2021 |access-date=17 October 2017 |publisher=Encyclopædia Britannica}}</ref> Some libraries have additional galleries beyond the public ones, where "reference" materials are stored. These reference stacks may be open to selected members of the public while others may require patrons to submit a "stack request" –  a request for an assistant to retrieve the material from the closed stacks: see [[List of closed stack libraries]].

Larger libraries are often divided into departments staffed by both paraprofessionals and professional librarians. Their department names and occupational designations may change depending on their location and the needs of the library.
* Circulation (or Access Services/Stacks Maintenance) – Handles user accounts and the loaning/returning and shelving of materials.<ref>Morris, V. & Bullard, J. (2009). Circulation Services. In ''Encyclopedia of Library and Information Sciences'' (3rd ed.).</ref>
* [[Collection development|Collection Development]] – Orders materials and maintains materials budgets.
* Reference – Staffs a [[reference desk]] answering questions from users (using structured [[reference interview]]s), instructing users, and developing library programming. Reference may be further broken down by user groups or materials; common collections are [[children's literature]], [[Young adult fiction|young adult literature]], and [[genealogy]] materials.
* Electronic Library – Responsible for providing information to users via electronic means.
* Technical Services – Works behind the scenes cataloging and processing new materials and deaccessioning [[Weeding (library)|weeded materials]].

Basic tasks in [[library management]] include planning acquisitions (which materials the library should acquire, by purchase or otherwise), classifying and preserving items (especially rare and fragile archival materials such as manuscripts), deaccessioning materials, patron borrowing, and developing and administering library computer systems and technology.<ref>{{Cite book |last1=Stueart |first1=Robert |title=Library and information center management |last2=Moran |first2=Barbara B. |last3=Morner |first3=Claudia J. |publisher=Libraries Unlimited |year=2013 |isbn=978-1-59884-988-2 |edition=Eighth |location=Santa Barbara |oclc=780481202}}</ref> More long-term issues include planning the construction of new libraries or extensions to existing ones, and the development and implementation of outreach services and reading-enhancement services (such as adult literacy and children's programming). Library materials like books, magazines, periodicals, CDs, etc. are managed using a library classification system such as the [[Dewey Decimal Classification|Dewey Decimal]] Classification Theory, though libraries will usually adjust their classification system to fit their needs.<ref>{{cite journal |last1=Bhattacharjee |first1=Pijush Kanti |date=2010 |title=Modified Dewey Decimal Classification Theory for Library Materials Management |url=https://www.ijimt.org/list-24-1.html |url-status=live |journal=International Journal of Innovation, Management and Technology |volume=1 |issue=3 |pages=292–94 |archive-url=https://web.archive.org/web/20220117232540/http://www.ijimt.org/list-24-1.html |archive-date=17 January 2022 |access-date=24 February 2022}}</ref>
The [[International Organization for Standardization]] (ISO) has published several standards regarding the management of libraries through its Technical Committee 46 (TC 46),<ref>{{cite web |title=ISO – Technical committees – TC 46 – Information and documentation |url=https://www.iso.org/iso/standards_development/technical_committees/list_of_iso_technical_committees/iso_technical_committee.htm?commid=48750 |url-status=live |archive-url=https://web.archive.org/web/20100703090332/http://www.iso.org/iso/standards_development/technical_committees/list_of_iso_technical_committees/iso_technical_committee.htm?commid=48750 |archive-date=3 July 2010 |access-date=7 March 2010 |publisher=ISO.org}}</ref> which is focused on "libraries, documentation and information centers, publishing, archives, records management, museum documentation, indexing and abstracting services, and information science". The following is a partial list of some of them:<ref>{{cite web |title=ISO – ISO Standards – TC 46 – Information and documentation |url=https://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_tc_browse.htm?commid=48750 |url-status=live |archive-url=https://web.archive.org/web/20100703204803/http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_tc_browse.htm?commid=48750 |archive-date=3 July 2010 |access-date=7 March 2010 |publisher=ISO.org}}</ref>
