Material Selection/ Collection Development Policy

Materials Selection/Collection Development Policy
(For all italicized print see page 7 for the exact wording of 15 CSR 30-200.015 Library Certification
Requirement for the Protection of Minors)
The purpose of the Mercer County Library is to provide all individuals in the community
with carefully selected books and other materials to aid the individual in the pursuit of
education, information, research, pleasure, and the creative use of leisure time.
Because of the volume of publishing, as well as the limitations of budget and space, the
library must have a selection policy with which to meet community interests and needs. The
materials selection/collection development policy is used by the library staff in the selection
of materials and serves to acquaint the public with the principles of selection. Selections will
be made and placed in the correct section according to their content and age appropriation.
(See Appropriateness by age of materials for selection guidelines, these guidelines are a
recommendation). Aligned to Administrative Rule 15 CSR 30-200.015 (A) The Library Bill of
Rights and The Freedom to Read Statement have been endorsed by the Mercer County
Library Board of Trustees and are integral parts of the policy. The materials
selection/collection development policy, like all other policies, will be reviewed and/or
revised as the need arises.
Responsibility for Selection
The ultimate responsibility for selection of library materials rests with the library director
who operates within the framework of the policies determined by the Mercer County Public
Library Board of Trustees. This responsibility may be shared with other members of the
library staff; however, because the director must be available to answer to the library board
and the public for actual selections made, the director has the authority to reject or select any
item contrary to the recommendations of the staff.
Appropriateness by Age of Materials selected for Youth
Library collections for patrons 18 and under have always been split into 3 different
collections. These collections are marked with “E” for easy, “J” for juvenile and a “YA” for
young adults. Books located in the “E” collection are intended for ages birth to 2 nd grade, the
“J” collection are intended for grades 3 rd through 8 th , and the “YA” collection are intended for
9 th grade and above. In alien to Administrative Rule 15 CSR 30-200.015 (A)
Criteria for Selection
1. The main points considered in the selection of materials are:
? a. individual merit of each item
? b. popular appeal/demand
? c. suitability of material for the clientele
? d. existing library holdings
? e. budget


Potential Problems or Challenges
The Mercer County Library recognizes that some materials are controversial and that any
given item may offend some patrons. Selection of materials will not be made based on
anticipated approval or disapproval, but solely based on the principles stated in this policy.
Responsibility for the reading of children rests with their parents or legal guardians.
Selection of library materials will not be inhibited by the possibility that materials may come
into the possession of children Aligned to Administrative Rule 15 CSR 30-200.015 (C). Library
materials will not be marked or identified to show approval or disapproval of their contents,
and no library material will be sequestered except to protect it from damage or theft.
Challenged Materials, Programs, or Displays
Although materials, presentation, and displays are carefully selected, there can arise
differences of opinion regarding suitable materials, presentations, events or displays.
Patrons who live in Mercer County and carry a current library card, requesting that
materials, presentations, events, or displays be withdrawn from or restricted within the
collection or library may complete in full a "Statement of Concern About Library Resources"
form which is available in the library. Aligned to Administrative Rule 15 CSR 30-200.015
The inquiry will be placed on the agenda of the next regular meeting of the Mercer County
Library Board of Trustees.


Statement of Concern about Library Resources Form
The suitability of books, presentations, events, displays or other materials for the library
collection may occasionally be questioned by individuals or groups. Patrons are free to enjoy,
dislike, or ignore any item in the collection, any program presented by the library, or any display
at the library. The library does not endorse opinions contained in its materials, programs, or
displays. Aligned to Administrative Rule 15 CSR 30-200.015 (C,D,F).
The library believes that censorship is purely an individual matter and declares that while
anyone is free to reject materials, programs, or displays for him/herself, that individual cannot
exercise this right of censorship to restrict the freedom of other persons to any materials,
programs, or displays. A request to remove library materials, programs, and displays creates
complex legal and ethical questions for both the library and the community. Consequently, this
issue is taken very seriously by the library and will be viewed objectively and as an important
Request to withdraw an item, presentations, events, or display—if a request is presented the
material, presentation, event, or display in question will be reviewed in its entirety, meaning
passages will not be taken out of context. Materials, presentations, events, or displays being
reviewed will not be removed from circulation, presentations or events will not be canceled, and
displays will not be disassembled until a decision has been made. For your request for review,
you must be a registered card holder of the Mercer County Library and a resident of Mercer
County. This form must be filled out by an individual, not a group. The form must be filled out
completely and signed. Aligned to Administrative Rule 15 CSR 30-200.015 (C,D,F)
