“The bangor mechanic association has the right to appoint four members of the board of directors.”
“A draft copy of the federal form 990 was reviewed by the finance committee and provided to the board prior to submission.”
“Conflict of interest questionnaires are periodically circulated to the officers and trustees to complete and are reviewed by the board of directors to ensure compliance with the conflict of interest policy.”
“The board reviews the performance of the library director annually and adjusts the director's compensation as it deems appropriate based on benchmarking.”
“Documents are available in the business office. Any person may request to see financial statements, form 990, board minutes, or other documents open to the public. Documents are available when business office staff are working, if requested at times when the library is open, but business office staff are not available, the documents will be provided on the next business day.”
“The bangor public library strives to inspire, enlighten, and enrich its members by connecting them to books, information, and ideas needed for work, recreation, education, and inspiration by providing excellent library service to its members and community.”
“Adult services: the bangor public library contributes to the prosperity and growth of the bangor region by providing library services to bangor residents and non-residents. Last year the library's adult department circulated 135,497 volumes to 27,751 registered adult borrowers. Nearly 144,400 people, or an average of 493 people a day, visited the library to check out books, magazines, dvd's, and audio books or to use public access computers or the high speed wifi, or to read in its reading rooms and study spaces. The reference department answered 14,271 questions from the public. The local history and special collections area offered local archives, books, maps, and microforms to aid those looking for the history of our region and to help those doing genealogical research. The library provides regularly scheduled book delivery to retirement communities and nursing homes and home delivery to homebound elders.”
“Virtual and special services: the library's website was viewed 225,124 times. As well as 41 public access computers used by 9,109 people (an average of 31 people a day), and the high speed wifi used on the top five routers by 16,778 users an average of 57 people a day, the library has a computer lab to provide both computer classes and one-on-one tutoring. The library provides access to e-books, e-audio books and e-magazines and 9 paid on-line e-resources over and above those offered through the state library. These resources include american ancestors, jstor, consumer reports, great courses and on-line sources to help local businesses including data axle reference services and demographics now. Views and usage of digital services were 86,101. The library offers a digital commons to provide access to collections of rare and fragile materials including the library's wwii posters and regimental histories as well as maps, photographs and yearbooks. The library works with high school and middle school students to make digital exhibits for the maine memory network. The library provides meeting rooms for outside organizations to use. Last year 1,596 meetings were held in the library's space. It also hosts exhibits, programs and special events. It has monthly art exhibits by local artists in its 4 galleries. It is the music library for the bangor symphony, is part of the downtown arts collaborative and serves as the major sponsor of the bangor book festival. Programs last year ranged from jazz to poetry, astronomy to history and economics to politics. The library creates original online programming that mirrors some of its traditional in-person programs.”
“The library periodically receives works of art as gifts from donors, and has elected, as permitted under sfas 116 (asc 958360-25), not to report the value of these works of art in its revenue statement and balance sheet.”
“The purpose of the endowment fund is to generate income to be used to help meet the operating and non-operating costs of the bangor public library.”
“Accounting principles generally accepted in the united states of america require management to evaluate tax positions taken by the library and recognize a liability if the library has taken an uncertain position that more likely than not would not be sustained upon examination by the internal revenue service and state taxing authorities. The library is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.”
